Friday Night Lights and Monday Highlights

Very early Friday morning, I caught the waning moon approaching Jupiter and Aldebaran. You could draw a line from Venus to Moon and cross over or near Jupiter. The skies were clear and should stay clear throughout the day and into the night, with a forecasted high in the mid-80s, twenty degrees below what we’ve been experiencing for the past several weeks.

Friday at work was a whirlwind of meetings, including one held off site at another local law firm. I got home a bit early because one of my vanpool riders took the day off, but within fifteen minutes of getting home, my son and daughter-in-law arrived from their all-day road trip from North Texas. We visited with them for an hour and half, when they left to drive into Kansas City to spend the evening with several of their friends who still live in the area.

Terry cooked an excellent southern comfort food type dinner of chicken-fried minute steaks, organic green beans with turkey bacon, mashed potatoes and home-made white gravy. Too bad the kids didn’t hang around long enough to chow down with us. Terry and I let our food digest a bit, watching the Olympics until the skies darkened enough for some star gazing.

I grabbed the XT8 (affectionately known as ‘Dob’) and carefully carried it out to the lower backyard. This time I took a small table to put my charts on. I set my case of eyepieces on the ground. I brought out the Intelliscope handheld device to attempt an alignment. This device, unlike my ETX-90’s AutoStar, is only used to identify objects, not ‘go to’ them (since the XT8 does not have any motors). The Intelliscope can help you find objects with a warm/cold kind of seeking system. I still haven’t bought a stool to lean against, so my back aches a bit this morning. I did a two star alignment, finding and centering Arcturus first, then Vega.

I wanted to revisit the Double Double in Lyra to both confirm that I could find it by star hopping and to attempt to see the double within the double. I asked the Intelliscope to ID what I had centered in the eyepiece and it claimed I’d found the Crab Nebula. Hmmm. That’s in the constellation Taurus, which isn’t visible until early morning hours in the east. I must have done something wrong in the alignment process. I powered off the Intelliscope device and made a note to myself to re-read the manual in the morning. Since I’d already found Vega, I spent several minutes comparing my star atlas to what I was seeing in the finderscope. I found Epsilon Lyrae and observed it with 26mm, 15mm, 9mm and a 2x barlow (using the 26mm and 15mm). Despite the apparent clearness of the skies, I did detect some haziness and thin stratus clouds overhead. That may have inhibited my ability to split the doubles within the doubles.

I hopped over to Albireo in Cygnus, just to make sure I could find it again without referring to my star atlas. I used a trick I had read about from some artists who do astronomical sketching where you defocus the stars, especially doubles, to discern their different colors. I did this while observing Albireo and I could clearly see the red and blue for each star in the double. I stretched my back for a few minutes and stared off to the northeast, at Cassiopeia, which I could clearly see as a distinctive ‘W’ shape. I could not see the constellation Perseus, but I did see one or two meteors radiating from the space between Cassiopeia and where Perseus should have been visible (but wasn’t because of the haze and light pollution from the prison just north of my location).

I returned to the scope and began a star hop around Lyra in search of M57, also known as the Ring Nebula. This was a test, for me, not only of my ability to find this fuzzy smoke ring, but also of an 8-inch telescope’s ability to cut through the obstacles inherent at my closest observing site (my backyard). I surprised myself. I found the nebula, quicker than I thought I would, and I even saw it through the finderscope. It probably helped that Lyra was almost straight up above me and the telescope, meaning I had less atmosphere to peer through. Using averted vision, with the 9mm, I could clearly see the ring. I used the background stars to focus, because you can’t really focus well on a smudge that’s fuzzy and faint.

Since I found and saw a nebula with the XT8, I wanted to see if I could find a globular cluster next. And I just happened to know where one was. M13 in the ‘armpit’ of Hercules (see chart above) happened to be overhead, somewhere between Altair and Arcturus. I had some trouble locating the stars that make up Hercules with my naked eye. I took several minutes, stretching my back, to peer overhead, but towards the west, and Arcturus. Eventually, the star dots connected in my mind’s eye and I found the constellation. I oriented the XT8 to the general vicinity where I thought M13 would be. I think I saw it through the finderscope, although I can’t remember specifically. Using the 26mm eyepiece, I centered the globular cluster in my field of view and proceeded to observe this large dense cluster for several minutes with various magnifications.

I stared off into the northeast again, still trying to find Perseus and also Pegasus. If I could see the Andromeda Galaxy (also known as M31), I would achieve a triple crown of astronomical observing from my backyard with the XT8 (1: nebula; 2: globular cluster; 3: galaxy). I spent nearly a half an hour, roaming around my backyard, changing my point of view and line of sight to the northeast and east. I found Cepheus, but no matter how hard I squinted or averted my eyes, I could not clearly identify the box that makes up the body of Pegasus. Frustrated, and with an aching back, I decided to call it a night at about half past eleven o’clock.

I returned the telescope to the band room and replaced all the dust caps. I hugged my hubby, for he had brought me a refreshing freshly made strawberry lemonade to enjoy while bending over the telescope for hours. Off to bed and sleep, at least until the dogs started barking when Derek and Royna returned home (sometime after midnight and before five – not exactly sure as I tried to sleep through the commotion).

My alarm only fires off on weekdays, but most days I wake up fifteen minutes early. Not Saturday morning though. When I cleared the sleep from my eyes and checked the clock on my cell phone, it read 5:45 a.m. and I could already tell the eastern horizon was brightening. I grabbed the tripod and camera and went out to the driveway to take a photo of the Moon approaching Jupiter.

Waning Moon Approaching Jupiter (Sat morning Aug 11, ’12)

If I happened to live in the Pacific, today I would be able to observe the moon occulting Jupiter. But I won’t be too disappointed, since I can observe the moon occulting Venus next Monday afternoon, between 3:00 and 4:00 p.m. I plan to take a pair of binoculars and my camera equipment with me to work. I will setup on the top of the parking garage and hope I have a clear line-of-sight through the buildings to the west to see the occultation as it occurs.

But tonight I plan to find a dark sky location and take in as many meteors as I can, raining down from Perseus. I better take a nap this afternoon and set an alarm for one o’clock Sunday morning. Don’t want to miss the best meteor show of the year!

Star Party Sign In (click image for rest of album)

My dad contacted me Thursday to coordinate conveyances for our weekend astronomical adventure, thinking we would be attending the monthly ASKC club meeting, but he was a week early. Since I had mentioned earlier in the week a desire to see the glorious summer spread of our own Milky Way Galaxy, he had called me several times the past few days to see about driving to northern Atchison county to escape the Kansas City area light pollution. Both Wednesday and Thursday evenings turned out to be hazy and cloudy, so we nixed the road trip north.

Instead, I suggested we attend the monthly star party at Powell Observatory. I received two confirmation e-mails from David Hudgins, the club’s star party coordinator extraordinaire. I decided to leave my scope at home because you don’t really need a scope to take in the Milky Way Galaxy. If the skies grew dark enough, it would stretch from the southern horizon, up over the top, clear to the northern one.

I thought perhaps I was reliving last Friday (that would be the 13th) because when I got home early (by ten minutes) I walked into some surreal drama. I won’t go into the stressful week at work (we’ve all had weeks like that), but I looked forward to forgetting work and ignoring the excessive heat by reading books and watching movies in a quiet, air conditioned home with my hubby and two Rotties. I came home to find our satellite on the fritz and Terry needing me to pickup a prescription before the pharmacy closed at seven. While he cooked dinner, I did some preliminary troubleshooting of the satellite system with little success and decided to call DirecTV customer service, knowing I’d probably be on hold for several minutes. The technician wanted us to disconnect, check and reconnect all of our cables, which seemed a ridiculous request since the cable runs are static and have not been touched, moved or manipulated in years. After almost ruining supper in an effort to jump through DirecTV tech support hoops, we hung up on them and sat down to eat.

By now, I had less than an hour to pickup the prescription, so I grabbed my purse and drove to the store. I got as far as the pharmacy counter, where the assistant recognized me and had the prescription ready for me, but when I opened my purse, my billfold was missing. I had left it in the van because I stopped at Starbucks after work for a mocha frappacino treat for the drive home. Now I had to return home for my billfold and repeat the trip back to the pharmacy, a wasted trip, time and gas. When I returned home the third time, Terry had solved the satellite system glich. With our excessive heat and drought conditions, the ground supporting our satellite dish pole has dried up so far down into the ground, that the pole can now be easily moved back and forth and twisted on it’s concrete base. One of our dogs could have bumped into it and messed up the alignment. Terry used the signal strength meter diagnostics channel on the satellite receiver to dial the dish back in.

Hoping that would be the final challenge of the week solved for the moment, I called Dad just after seven o’clock and told him to head my way. I gathered up my camera equipment, my pocket star atlas, a large hardcover edition of Backyard Astronomy (to review Milky Way info), my purse (with billfold) and a lidded glass of cool water. I asked Dad to drive this weekend, volunteering to drive next weekend for the July club meeting. The hour jaunt to Louisburg passed quickly and we arrived at Powell just moments after sunset. The evening cooled off nicely, but remained calm, clear and surprisingly dry. In fact, we experienced no dew (the bane of telescope optics) until after midnight.

Sterling Scope — Mike Sterling collimating his telescope while my dad attends.

Several club members were already present and setting up their scopes in the East Observing Field (click photo above for photos taken upon our arrival). One member, Mike Sterling, introduced himself to me (asking if I was ‘the’ Jon Moss … apparently my name is known, if not my face or gender, from my blogging). He was in the process of collimating his 20-inch Dobsonian. My dad provided an extra pair of eyes to help finish. Mike also gave us a color brochure published by Astronomy magazine of the illustrated Messier catalog. This will come in handy in the future when I really get serious about an observing award.

The theme for this month’s star party centered around star charts and atlases. David Hudgins setup a table displaying several popular and easy-to-use books, visual aids and posters. I indicated to David I already owned the Sky & Telescope Pocket Sky Atlas and a smaller version of the wheel night sky star guide (the circular atlas resting on top of the poster in the upper left hand corner of the table shown in the photo above).

Dad and I wondered among the scopes, waiting for twilight to fade and the stars to emerge. Saturn and Mars, along with Spica and Arcturus appeared very early and most of the scopes honed in on our ringed neighbor. By 10:30 pm, the skies had darkened enough to begin hunting for some of the brighter Messier objects. Mike graciously asked me (several times over the course of the evening) what I wanted to observe next. I drew a blank every time because my goal had been to see the Milky Way, not any specific object viewable in a scope. He obligingly filled in the blank by touring through clusters, nebulae and a galaxy found in the constellation Sagittarius, Scorpius, Hercules and Ursa Major. I tweeted the objects as we found them so I would have a record of what we saw and when.

10:30 pm – M57 (the Ring Nebula), M20 (the Trifid Neblua), M8 (the Lagoon Nebula), M7 (the Ptolemy Cluster)
10:50 pm – M51 (the Whirlpool Galaxy)
What happened during the 11 o’clock hour? *see update below
12:00 am – M4 (globular cluster in Scorpius)
12:08 am – M13 (the Great Globular Cluster in Hercules)
12:24 am – M10 (globular cluster in Ophicuhus)

Brocchi’s Cluster, also known as the Coathanger: a conspicuous asterism easily seen with binoculars in the constellation Vulpecula (via Wikipedia)

My dad and I also used his binoculars just to see what we could see with them (as opposed to a scope). The highlight of that side project included finding Brocchi’s Cluster (more commonly known by the asterism ‘the Coathanger’). One of the other club members used the Summer Triangle as an aid to locating the Coathanger. As stated in the Wikipedia article: “It is best found by slowly sweeping across the Milky Way along an imaginary line from the bright star Altair toward the even brighter star Vega. About one third of the way toward Vega, the Coathanger should be spotted easily against a darker region of the Milky Way. The asterism is best seen in July-August and north of 20° north latitude it is displayed upside down (as in the picture above) when it is at its highest point.”

* Update * (added after original publication):

I completely spaced out tweeting during the eleven o’clock hour. During this time, Mike disconnected the Goto electronics on his telescope and set me to star hopping for objects near Sagittarius. The first one he tested me with was finding two small globular clusters a small hop away from the gamma star in Sagittarius (the star the delineates the spout of the teapot). If I could find these two clusters, Mike told me I should be able to see both of them at the same time in the eyepiece’s field of view. After about five minutes, I spied a couple of small fuzzy balls, not as distinct as the surrounding background stars, but I thought they might be the clusters. Mike confirmed I had found them by doing a ‘happy dance’ and sing-songing ‘she found them, she found them’ for all to hear. The designations for these clusters are NGC 6522 and 6528.

Mike next set me to finding either M69 or M70 (also hanging out in Sagittarius, but in the bottom of the Teapot). I glanced at his star chart and used his excellent Telrad finderscope (which had a nice large field of view and an easy-to-use red bullseye) to quickly locate one of the Messier objects (probably M69). Again Mike did a happy dance and song.

Mike went looking for another globular cluster, this time between Sagittarius and Scorpius, designated as NGC 6380. I found this one especially interesting because of it’s apparent close proximity to a star.

The third test proved my undoing. Mike moved his scope to Antares in Scorpius and set me to finding M4. I didn’t review his star chart and spent several minutes attempting to find it. Eventually, I gave up and Mike located it.

Teapot Asterism (for Sagittarius constellation)

Despite all the mesmerizing Messier distractions, I did succeed in observing the vast sweep of our Milky Way Galaxy. I learned a couple of cool memory aids and bits of trivia about finding the ‘heart’ of the galaxy and the path it takes. Cygnus, the swan constellation, also sometimes known as the ‘Northern Cross,’ flies along the Milky Way, pointing directly to the heart of the galaxy. To find the Milky Way’s heart, locate the Teapot (an asterism for the constellation Sagittarius), visible along the southern horizon during July and August, and imagine steam rising from the spout.

I even attempted to photograph the Milky Way using my simple tripod and DSLR camera, but without an equitorial mount of some kind with a tracking system and the digital photo editing software (to stack multiple repetitive exposures), the best I could accomplish was a three or four second exposure (using ISO 800) and fiddling with the brightness/contrast after downloading:

Steaming Teapot (tilted slightly so that the Milky Way
appears centered/parallel to the frame of the photo).

I also took photos of Cygnus swimming in the Milky Way, the Summer Triangle, the Big Dipper over the dome of the observatory and several of the southern horizon. To see the entire album, click on the photo at the top of this blog.

Soon after 12:30 a.m., Dad and I thanked Mike Sterling for the guided tour of the summer sky. We packed up our gear and drove the hour home, where I finally drifted off to sleep after two o’clock with visions of Messier objects dancing in my head.

Dad and I had a blast and my husband is now having second thoughts about staying home last night. Many thanks to David Hudgins, Mike Sterling and the other members of the Astronomical Society of Kansas City for throwing a fun mid-summer star party.

Heat Bubble Bursts Just in Time for Summer Stargazing

Saturday evening I headed south to Louisburg to volunteer for my second scheduled night of the 2012 Powell Observatory public season. My dad decided to tag along, to enjoy the show and help keep me awake for the long drive home. We left Lansing about twenty minutes after five and my car’s external thermometer reported 106 to 107 degrees, which has been our afternoon average for about a week now, give or take two or three degrees either way. We stopped in Bonner Springs to grab a quick, cool sandwich from Subway and returned to the highway just shortly after six o’clock. I needed to be at Powell Observatory by seven o’clock to help prepare the facility for the weekly public program and observing night.

As we approached Louisburg from the north, I noticed a definite increase in the wind, so much so that my car was jostled several times. At the same time, I noticed a significant drop in the external temperature. By the time I exited US-69, the thermometer read 92 degrees, and was still falling. Except for early mornings the past couple of weeks, I had not seen or felt such low temperatures while the sun still shone. I pulled into the west observing field parking area and realized I was again the first person to arrive. Since the temperature had dropped, I turned off the car and opened all the windows. The breeze felt incredibly refreshing.

My team leader arrived within a few minutes and I received my Powell Observatory ‘Staff’ T-shirt, which I changed into as soon as the building was unlocked. I helped setup the class room for the program, ‘Sounds of Space.’ Another ASKC member arrived and setup his ten-inch Dobsonian for solar observing and I caught a glimpse of some great sunspots before our public guests began arriving. The clouds provided some dramatic solar observing situations.

I repeated my role as gatekeeper and accepted donations from the public and queried them for their ZIP codes to record for future grant petitions. The first group of twenty-five guests began the ‘Sounds of Space’ program at 8:30 p.m., but I soon had at least that many waiting for the second showing. At one point as I sat waiting for more guests to arrive, what I thought was a stray dog wandered into the observing field, soon followed by three horses, two with riders and a third colt between them. They trotted across the field to the west, with the dog trailing after, riding off into the sunset … literally.

As the sky continued to darken, despite a few wispy clouds, we opened the dome so those waiting for the next program could observe Saturn and a globular cluster found in the constellation Scorpius. I didn’t get a chance to look at the cluster through the 30-inch scope, but I believe they looked at M4, which is near the bright star Antares.

We ended up having nearly ninety public guests Saturday evening and ran a third showing of our program. After the last two guests had left the dome a bit after eleven o’clock, I quickly snuck a peak at the Ring Nebula in the constellation Lyra, one of the Messier Objects I’ve been trying go get a glimpse of for quite some time. Lyra is also home to the very bright star Vega, one of the three stars that form the Summer Triangle.

As the final guests drove away, my team members and I began cleaning the building and storing chairs, tables and other items for the next Saturday. I signed myself out of the Observatory at 11:35 and gathered up my dad for the long drive home. He related information he’d gleaned from another team members about various types of Dobsonian telescopes and helped keep me alert as we sped north towards Leavenworth County.

Next week, we present a program on ‘Our Amazing Moon’ and the following week we’ll pose the question ‘Is There Life Out There?’ We look forward to showing you the astronomical sights (and sounds).

Until then, Keep Looking Up!

My Mini-Messier Marathon

Venus, Jupiter and New Crescent Moon (Fri 23 Mar 2012)

I left work Friday afternoon in a pouring rain. Nothing unusual in the grand scheme of things. It is late March and Spring had sprung this week, which usually brings rain. An entire week of rain, in fact. I had hoped, against all evidence to the contrary, that the rain would let up earlier in the day on Friday. I resigned myself to retrieving my vanpool riders and slogging through rain drenched traffic for the next hour. I wanted to participate in my astronomy club‘s Messier Marathon, but just didn’t think the effort would equal the returns. I would have to pack up all of my astronomical observing equipment (telescope, tripod, eyepieces, control device, cables, portable battery, sky charts, observing aids, red flashlight, chair, some kind of table, etc) and then drive over an hour to the dark sky site way south near Butler, Missouri. Early indications from other club members reported the dark sky site field was very wet and since I don’t own a four-wheel drive truck or SUV, I decided to stay in Lansing.

I had permission from my city council representative to contact the Chief of Police to make arrangements to use one of the city parks after dark. I hesitated to bother the police. That is a huge hassle to overcome, for me anyway. And I still needed to re-train my telescope’s Alt/Az drives before packing them up, since that process requires daylight and a terrestrial object to focus upon. Clouds still scudded across the sky while I set the telescope up outside on the lower back patio. I trained the drives for five or ten minutes and then powered down the telescope until later in the evening.

Venus, Jupiter and the CrescentMoon — Venus, Jupiter and the Crescent Moon

After watching a couple of episodes of Jeopardy and squeezing in my exercise routine (and making my legs wobbly and rubbery by trying a longer version of one of the higher intensity activities), I slipped back outside to see how many stars were visible at just a few minutes past eight o’clock. I spied the small sliver of a new crescent moon hovering just over my neighbor’s roof so I grabbed my camera (already on it’s tripod) and took a few photos (two of which I am including in this post). I even got Terry outside long enough to witness the new moon and point out how much higher Venus has gotten over Jupiter in a week since the last time I photographed the pair of them.

By the time I finished snapping a few photographs, I had enough bright stars to attempt an alignment of the telescope with my newly retrained drives. The Autostar easy alignment selected Sirius in Canis Major as the first star in the alignment process. After I found and centered the Dog Star, the next stop on the alignment workflow became Capella in the constellation Auriga, another easily spotted star in the evening sky. The Autostar reported a successful alignment so now for the first real test of the retrained drives. I instructed the device to find Jupiter. Surprise! The telescope found Jupiter on the first try! I did have to recenter Jupiter and it’s four glorious moons in the eyepiece, but I did not have to use either of my finder scopes. I inserted a 2x barlowe and a 26mm eyepiece and could clearly see the cloud striations on Jupiter. I could even see a hint of color. I again pulled Terry out to the telescope to take a look at the gas giant and its beautiful alignment of moons.

Next stop on my pre-Messier tour became Venus. Again the Autostar found our sister planet successfully. I only had to re-center the very bright planet in my eyepiece. I should have put a filter on the eyepiece, because even at only half-full, Venus almost hurt my eyes to look at. I felt confident enough in the telescopes alignment and the retrained drives to begin my mini-Messier Marathon.

My Messier Marathon Observer’s Form lists the objects in a ‘best viewed in this order’ arrangement. I knew I would not be able to observe the first two items on the list, due to the nature of my site. My house rests in a valley, behind a large hill to my west. In addition, I have several tall trees in my backyard, as do my neighbors to the west and north. Thanks to the highway just a couple of blocks to my west, I have ample ambiance (aka light pollution) and nearly all my neighbors must be afraid of the dark because they insist on illuminating nearly all exterior surfaces of their residences. Still, I told the Autostar to go find M77, a spiral galaxy also known as Cetus A. Unfortunately, the telescope came to rest pointing northwest, through at least three trees. I moved on to the next item, M74, another spiral galaxy in the constellation Pisces. But again, I saw only trees. A shame, really, as I would love to see that beautiful spiral galaxy (shown in photo above and to the left).

The next three stops on the observation list also happened to be galaxies, including the famous Andromeda galaxy, designated as M31 on the Messier list of objects. Since the telescope did not move appreciable away from the area of M77 and M74, I again couldn’t see the stars for the forest. Yet another galaxy I desperately want to observe, so to ease the pain of defeat, I’ll provide another image of that marvelous gem. The image above and to the right also includes M32, one of the other two galaxies I couldn’t observe.

I began using my Sky & Telescope Pocket Sky Atlas to assist me in locating Messier objects that I could actually view in my limited sky scape. The Pocket Sky Atlas‘s last pages contains an index of Messier objects and the star chart they appear on. I skimmed through the list of the next few objects and determined that M45 could be seen with the naked eyes. The Pleiades is an open star cluster. I still told the telescope to go find it and spent a few minutes marveling at the cluster of bright stars peering back at me through the eyepiece. Finally, I got to check off one of the 110 objects on my Messier Marathon Observer’s Form, writing 8:42 p.m. in the blank provided.

The next two objects I found easily included M42 and M43, both found in Orion’s sword and more commonly known as the Great Orion Nebulae and De Marian’s Nebula (really part of the other one or an extension of it). I wrote 9:07 p.m. in the blanks on my form.

I spent the next thirty to forty minutes trying to track down several objects I should have been able to find since they were south or directly overhead. I could not find the Crab Nebula (M1) and began to suspect I had messed up the alignment on the telescope. I had nudged a tripod leg more than once, so I reverted the Autostar to star mode and went searching for Rigel, Betelgeuse, Sirius and Capella again to retune the alignment. After that, I was successful in viewing several star clusters, including M44 (aka the Beehive Cluster), M48 and M50 (between 9:45 and 9:51 p.m.).

Supernova SN 2012aw (pointed at by arrow) is located in the outer arm of the barred spiral galaxy M95 in Leo. Greek amateur Anthony Ayiomamitis obtained this view on March 20th from his home outside of Athens. Image from Sky & Telescope article.

I got even more excited when I spied M95 on the list just two below M44. This spiral galaxy gained fame this past week by spouting a supernova. My earlier research also showed that Mars was just a few degrees away from M95. So I took a few minutes to realign the telescope and enjoy the ruddy beauty of the fourth planet in our solar system. Then I went on the hunt for M95. I spent many frustrating minutes attempting to find the elusive spiral galaxy but to no avail. The skies above Lansing are just not dark enough for my small telescope. It can’t gather enough light and my aging eyes can’t ever seem to get acclimated to the annoying and obscuring local ground illumination to spot such a faint (9.7 in magnitude) object. By a quarter after ten, I decided enough was enough.

And, for some unknown reason, the telescope had twice decided to go off on a tangent, causing the altitude drive to run off for no reason and would not stop when I entered commands into the Autostar. Hmmm. There must be a bug in the latest firmware I downloaded last week. I should probably hook the laptop up to it today and see if a ‘fix’ has been made available from Meade.

I enjoyed my mini-marathon of Messier objects and learned quite a bit about my abilities and the capabilities of my amateur astronomy equipment. Tonight I will attend the monthly meeting of the Astronomical Society of Kansas City and tomorrow I will probably head south to Powell Observatory for a training session on the club’s large telescope. By Monday, I should have purged my system of all astronomical cravings, at least until the next new moon.

Bright Evening Star at Dark Moon

I got home from work yesterday before 5:15 p.m., leaving me plenty of time before the sunset to walk Apollo. Terry got him so excited, whispering the word ‘walk’ in his eagerly raised ears. By the time I had changed my clothes and laced up my walking shoes, Apollo was whining and jumping around the living room. I grabbed my water bottle and the leash and off we went for a quick forty-five minute walk.

Once back home, I dashed down to the basement and unburied the telescope equipment from last week’s water heater install which necessitated a redistribution of the junk languishing down there. The last thing I brought up to the band room was the large tripod. I took it out the patio door and set it up on the strip of concrete patio just south of the hot tub. I took the case of lenses out to the hot tub wooden steps as well as the box containing the hand-held device that controls the telescope, helping to align it and find objects in the night sky.

I took the telescope out of its box and secured it to the tripod’s base. Something didn’t look quite right. I dug out the manuals for the telescope and the tripod, but nothing would focus. Ah, I needed my reading glasses! I ran upstairs and grabbed them off the kitchen table. Much better! I refreshed my aging memory on the finer points of placing the telescope correctly on the tripod. I disconnected the telescope, turned it 180 degrees and re-secured it to the base. Then I aligned the tripod legs more-or-less on a north-south orientation. Finally, I was ready to connect to Autostar hand-held control device and the 12-volt power supply.

I looked over my shoulder to the southwest and could already see Venus and Jupiter in the still lit dusky sky. I plugged in the power supply and the Autostar and flipped the switch at the base of the telescope to the on position. The Autostar woke up and warned me not to look through my telescope, ever, at the sun directly. Well, darn, the sun had already set so I didn’t really need to worry about that.

I entered today’s date and time and told the Autostar that, no, currently I wasn’t using daylight savings time. I skipped the alignment, since I couldn’t see any stars yet, and, from past experience, the stars it would want to use for aligning the telescope would be blocked by either my house (which rose thirty feet high to my east only about six feet away from the base of the tripod) or the trees in my backyard (a very tall pine tree, tall maple tree and my neighbor’s large pear tree – all block my western, northwestern and north horizons from my backyard). Basically, I can only look up, to the south or southwest, with a mostly unobstructed view from my back yard. Oh, and there’s a large hill about a quarter of a mile to my west, so I can’t really see the sunsets either.

Using my finder’s scope, I zeroed in on Venus and then programmed the Autostar to find Venus, without actually finding it. I found it in the Autostar’s database of observing objects and then told it to start slewing (also known as tracking the object so it always stays centered in the eyepiece). I put in my 26mm eyepiece and then paused the slewing. I used the directional arrow keys on the keypad to center Venus in the field of view and then unpaused slewing. Wow! Was Venus bright! But smaller than I anticipated. I tried a variety of lenses (16mm, 9mm and the doubling one with a combination of all of those) and got brave and tried three different types of colored filters.

I quickly read through the one page reference guide for the lenses, each of which gave tips for the various types of objects you could observe and what you could expect from the different colors. I first tried the blue filter, which helped reduce the glare from the still well-lit western sky. Venus was still very bright. I next tried the orange filter, which really brought down the brightness and I believe I even saw some cloud formations. The last color I tried was the green filter, but I don’t believe that one added to my viewing experience.

After observing Venus for several minutes with various filter and eyepiece combinations, I told the Autostar to go find Jupiter. Since I had not aligned the telescope previously, I had my doubts as to whether the computer and the drives could actually find it. I knew where it was, because I could see it. The Autostar got close, but not close enough to see Jupiter in my 26mm eyepiece. I pause slewing and used the finder scope and the directional controls to center Jupiter. I unpaused slewing and was amazed at the size and clarity of Jupiter and four of its moons.

The first thing that struck me was the fact that Jupiter looked at least as large as Venus had, if not larger! Yet Venus is closer to Earth by a long shot. This really made me wonder about the sheer size of Jupiter, all those billions of miles away, out past Mars and the asteroid belt. It’s own miniature solar system. Awesome!

All but one of Jupiter’s moons were lined up perfectly on one side of the gas giant. I could clearly see the striations in the clouds, but I did not see the Red Spot. I spent several very enjoyable minutes observing them all with various eyepieces, but no filters (as I could see detail very clearly without them).

My last longshot of the night was a whimsical hope that I would be able to see one of the nebulae in Orion. I told the Autostar to go find the Horsehead Nebula. Off it went, taking the telescope generally to the belt or sword area of the constellation Orion. I hadn’t yet grabbed my Sky & Telescope Pocket Sky Atlas, so I couldn’t remember exactly where the Horsehead Nebula resided in relation to Orion’s belt. I traversed up and down the sword, but did not further investigate the belt, where I should have concentrated. However, since the skies were still quite bright (not dark) and the light pollution continued to obscure my ability to see such dark nebulae, I gave up on that hunt and saved it for another night when I could transport my entire setup to a dark sky site. Thanks to a gift from my father, the prospect of observing at a dark sky site have gotten markedly better. He repaired an old portable emergency battery and light (both white and red) device that can be used as a power source, once I find (or buy) the power cord for the telescope that includes the standard car cigarette lighter-type connector.

On a whim, I told the Autostar to go find the Pleiades, another open star cluster I could easily see between Orion and Jupiter. I couldn’t easily find it listed in the observing objects database, so I looked it up in my Sky Atlas and determined it also had the M45 designation. The Autostar took the telescope to the general vicinity of the Pleiades, but I could not confirm this from the eyepiece. And, since the Pleiades were very high in the night sky, I could not use the finder scope to manually re-align the telescope. Why? Because on the ETX-90, the OEM finder scope becomes unusable at vertical or near vertical angles when using the Alt/Az mount (instead of the Equatorial mount). I have a replacement finder scope, but have not yet installed. Terry volunteered to give it a go this week since I left the telescope on its tripod smack dab in the middle of the band room last night.

I may or may not be able to participate in Sky & Telescope’s Moon Mercury challenge this evening. Tonight, about thirty minutes after sunset, the tiniest sliver of the new moon will be visible right next to Mercury. My drive in to work today produced a stunning sunrise, thanks to a mostly cloudy sky, so unless these clouds blow away before I get home, I doubt I’ll be able to see the sun, let alone the pencil-thin moon and the small bright fleeting dot of Mercury. If, by some miracle, the skies are crystal clear when I get home tonight, I will at least packup my digital camera and its tripod and find a spot on a hilltop with a clear unobstructed view of the setting sun.

Best Time to Spy Comet Hartley Two is Now

I tried several times this week to spot the comet Hartley 2 using my birthday preset as an assist. According to EarthSky’s blog, you should be able to find it with binoculars near the constellation Cassiopeia. Here’s a graphic from that blog posting to assist in pinpointing the comet:

Since tonight is October 9th, the comet is below the Double Cluster. I’m taking all the telescope equipment with me to Winfield today so I can make the attempt again tonight (since the moon is still very new and the skies are dark).

Happy comet hunting and keep looking up!

Terrestrial Triumps and Tragedies This Past Tuesday

Transferred from my MySpace blog (originally posted October 5, 2010):

Second star gazing journal. After calling Meade Support on Monday, I recalibrated the drives and retrained them as well as finally dialing in (for the most part) my viewfinder … all before the sun went down.

Then I packed everything up (carefully) and headed west to my local community park a couple of miles west of my park. I was a bit disappointed to see what appeared to be a soccer practice occurring even though the sun had set at five minutes before seven. Since I didn’t want a stray hyperactive youngster to knock over and destroy the expensive and sensitive telescope equipment, I resolved to wait until everyone left.

In the meantime, at five after seven, while sitting in my car, I could already see Jupiter with my naked eye … clearly the brightest object in our autumn evening skies.

I waited another thirty-five minutes before everyone finally left. So by 7:45 p.m. I was finally set up and ready to try again. I first manually found Jupiter and confirmed my viewfinder was centered and in sync with the telescope. It was for the most part. I then spent fifteen or twenty minutes looking at Jupiter and it’s moons. I started out with the 26x eye lens and then added the 2x barlow which really brought Jupiter in close and didn’t dim it too much.

By then it was dark enough to attempt an alignment. I aligned on Altair but didn’t recognize (nor now do I remember) the second star the AutoStar wanted to use for alignment. I centered on the brightest star I found in the viewfinder. Then I told it to find the constellation Cassiopeia and it tried, but ended up off by half a sky (basically looking southwest instead of northeast). I interrupted the sidereel so I could synch it by moving the telescope around to the correct portion of the sky. My goal was to attempt to find the Double Cluster near Cassiopea and eventually the comet Hartley 2 which is between the two (Cassiopeia and the Double Cluster). I didn’t have much luck, but I enjoyed viewing so many stars … layers upon layers of them.

Next, I then went in search of the binary star in the handle of the Big Dipper … Mizar and Alcor. That was easy to find and quite interesting to view.

Lastly, I focused on a bright flashing object in the northwestern sky. When I attempted to focus on it it appeared to flash green and red rapidly. (I later determined this flashing star was Arcturus and the red/green was caused by the Earth’s atmosphere).

Unfortunately, about that time, the local constabulary arrived with bright headlights (thankfully not pulling out the spotlight) to inform me he needed to close the park. I replied the posted sign stated the park was open until 10:00 pm. He rebutted my statement by saying it was supposed to close at sundown. I replied the posted sign did not state that caveat. So, I took one final look at Jupiter and it’s moon, then packed up the equipment and was home by 8:45. I barely got an hour’s worth of star gazing in.

I’ve learned, though, that my telescope probably needs to be serviced. Meade, in it’s proprietary wisdom, does not provide parts or service partners, so the telescope will have to be packaged and shipped to their world headquarters in California for service and repair. I’ll call them tomorrow to get the gory details.

I enjoyed a wonderful but short hour of moonless nearly perfect dark sky viewing. Not too cool, no wind, and not a cloud in the sky.

Keep looking up!
