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!

Moon Overtaking Jupiter and Venus

Venus Jupiter Moon — The moon overtaking Jupiter and Venus

I fell asleep amid visions of rainbows and towering gilded sunsets dancing in my head. I woke up to clear skies this morning. Clear enough that I drug the tripod out and stuck the camera on it for a few minutes during the five o’clock hour before the sun began bleaching the eastern horizon.

Jupiter still hugged close to Aldebaran, but the most surprising sight for me was Orion visible, appearing to be lying down on the eastern horizon. I could see most of the stars in that constellation, but the moon and Venus shone significantly brighter.

As the week wears on, the moon will pass by or through the two planets. I plan to take more early morning photos until the new moon. I am especially looking forward to the opportunity presented Sunday morning, when I may be able to capture Mercury in addition to the objects shown above.

I may be staying up all night Saturday to watch the Perseid meteor shower (if you follow that link to Sky & Telescope‘s web page, you’ll see a beautiful photograph taken by local phenom astronomer Fred Bruenjes, a fellow member of the Astronomical Society of Kansas City). The weather, in addition to being much cooler, may cooperate and keep the skies clear.

I should probably take a nap Saturday or go to bed early, and then get up after midnight and drive somewhere, probably northwest of my home, to a darker sky location. Then, I should be able to see more meteors streaking through the sky, than if I lounged around in my backyard, peering through the local light pollution and leafy tall trees. But I doubt I’ll be able to take a nap, because I am also expecting out-of-town visitors for the weekend.

No rest for the aspiring amateur astronomer.

Daytime Observing: Part Two

Just before one o’clock, I took a break from prepping the purple bedroom for ceiling painting and went down to the lower patio to try some solar observing with the XT8. The telescope was still in the shade (barely) but could be tilted into the sunlight out of the shadow of the house. This created the ideal observing site, for me at least, as I could stand mostly in the shade and still use the scope to observe the sun.

I removed the dust caps and installed the solar filter on the end of the tube. I selected a 28mm eyepiece, which would show me the entire solar disk. I looked down the tube to the ground and used the silhouette of the scope to orient on the sun (the smaller the shadow, the better aligned). Bingo! Found our closest stellar neighbor on the first try.

I could clearly see six sunspots. I tried the 15mm and the 9mm, but became disappointed in my inability to achieve a crystal clear focus when I zoomed into one of the sunspots. I nudged Terry away from his computer in the band room to see what he thought of the various eyepieces and how well they focused on the sunspots. He seemed to have the same experience I did. The 28mm provided the best and crispest view.

After a few minutes out in the heat, I decided enough was enough and brought the telescope back into the house, carefully putting away the solar filter in its protective cover and box.

Daytime Observing: Part One

I got stood up on my second date with Dob thanks to the clouds. I just wish the clouds had produced some much needed rain to relieve the extended drought Kansas and the rest of the Midwest is suffering under this summer. I woke myself up in the middle of the night, checked the night sky and could barely see the moon for the clouds, so stargazing was a bust.

Even later, when I work up again (around four thirty), I peered towards the eastern horizon and could almost see Jupiter and Venus through the thinning clouds. An hour later, I checked out the back side of the house and I could clearly see the moon. The clouds had left.

I eyed my small ETX-90, huddling in ‘time-out’ in the corner behind the couch. I thought about the XT8 downstairs in the band room. I debated with myself which one would be easiest to setup outside to observe the moon after the sunrise. The Meade is lighter, but requires the battery pack, Autostar hand controller and alignment. The Orion I could just carry outside and pull into position. The Orion won that coin toss handily.

I setup on the lower patio next to the hot tub. I grabbed my case of eyepieces and my Sky & Telescope Moon Map. I wanted to find a couple of more lunar features listed on the Astro Quest. With a 25mm eyepiece inserted into the focuser drawtube, I centered the moon in the field of view. Then I checked the finderscope’s alignment and fine-tuned it to match what I could see through the telescope.

I easily located the first feature: the Sea of Tranquility.

Next, I wanted to locate the Julius Caesar crater, which just happened to be located on the western edge of Mare Tranquillitatis.

I switched out eyepieces, using a 15mm and a 9mm. I attempted to use a 4mm, but could not get a clear focus or possibly enough light to discern any lunar features. I returned to the 15mm to do some close observations of the Julius Caesar crater.

I eventually tried to find two other features: the Alpine Valley and the Straight Wall, but I will need to wait for the terminator to create shadows in those areas before I can confirm the observation.

I left the XT8 outside, putting all the dust covers and caps back in place. I plan to take some time this afternoon and do some solar observing as well, since we are at the peak of the sun’s eleven year sunspot cycle.

My First Date with Dob

Friday evening I had my first opportunity to really dig in and learn about the telescope I borrowed from my astronomy club. A week ago, Terry and I returned to Kansas City to meet one of the club members at the Warko observatory on the roof of Royall Hall on campus at UMKC. I put in a request to borrow an eight inch Dobsonian telescope (shown at left) to compare and contrast its light gathering abilities with my own ETX-90 (a Maksutov-Cassegrain type telescope). I had high hopes since the aperture on the XT8 is more than twice as big. On the other hand, the ETX-90 is lighter. I drove the van, having hidden the middle set of seats in the subfloor, to make the initial transport of the telescope as easy as possible.

Fast forward an entire week to another Friday evening. After a quick rather disappointing dinner at the local Dairy Queen, Terry and I returned home to separate activities: he to a strings-only practice for one of his bands and me to setting up the loaner scope.

I moved the base into the great room (so called because it’s the biggest room in the house and has a high vaulted ceiling with a floor-to-ceiling corner fireplace). I then re-read the instruction manual, paying close attention to the section dealing with placing the optical tube on the base. The tube weighs just a bit over twenty pounds (the base is a couple of pounds heavier). I picked up the tube, holding it vertically, and rested it gingerly on the bumper stops. I inserted the tension and retaining knobs per the directions and then tested the altitude and azimuth mobility. The base seemed to stick a bit, but nothing that couldn’t be overcome with some nudging.

I attached the finderscope to the optical tube, but did not attempt to adjust it until later, when the tube would be outside and I could find an object to orient on a suitable distance away from my site. I removed the dust cover cap for the tube and for the eyepiece in anticipation for the next phase: collimation

XT8optimalcollimategraphic — When the mirrors are properly aligned, the view down the focuser drawtube should look like the graphic above (for the XT8 telescope).

I peered down the optical tube, past the secondary mirror and its spider support system at the large eight inch mirror nestled in the bottom. A small faint circle was inscribed on the surface of the mirror, assumedly in the exact center. I stepped around to the side of the tube and stared down through the eyepiece opening, where I could clearly see my own eye and the small circle mentioned above. My pupil and the circle did not line up exactly, as they should have (see diagram above left).

Upon further reading, and searching through the boxes and bags that the telescope came in, I could not find the collimation cap referenced in the instruction manual: “This cap is a simple cap that fits on the focuser drawtube like a dust cap, but has a hole in the center and a reflective inner surface. The cap helps center your eye so that collimation is easier to perform.” I forged ahead, hoping I could get the mirror aligned ‘close enough’ for some test observing later that night.

I followed the instructions carefully, reading and re-reading and comparing what I was seeing through the focuser drawtube with the examples provided in the manual. I decided the secondary mirror didn’t need any adjustments, just the primary mirror. The locking thumbscrews on the back of the mirror were already loosened, so I began experimenting with small turns of the larger thumbscrews to adjust the tilt of the primary mirror. I eventually got the small circle in the middle and tightened the locking thumbscrews down. Now to move the unit outside to align the finderscope.

I tilted the tub vertical, grasped the convenient handle on the back of the base with my right hand, keeping the tube vertical with my lefthand. I walked slowly out the back door on the patio and down to the lower level of my back yard, away from (as much as that is possible) the surrounding trees (mine and my neighbors). I needed to find an object about a quarter of a mile away to align the finderscope. Because I live in a valley (Fawn Valley to be precise), everything, including the ground, is up from my backyard, and most of the horizon is blocked by houses and trees. I could barely see the road leading up the hill to where City Hall stands, a couple of blocks to my south. That would have to do. I quickly and easily got the finderscope dialed in.

Now, I had to wait for darkness to fall. I brought out my eyepieces (the three that came with the scope I left in the box with the solar filter) so they and the scope could reach a temperature equilibrium with the outside environment. I went back inside and reviewed the Astro Quest observing award object list and my sky atlas to determine a short list of objects to observe before the moon rose high enough to wash out the night sky.

At half past nine, I went back outside, knowing I’d be able to find Saturn and Mars in the southwestern sky. I did and quickly tried nearly every eyepiece I had, from a 30 mm down to a 9 or a 4 mm. I doubled a couple of those using a 2x barlowe lens. I could clearly see the Cassini division in the rings, but did not try to discern any cloud variances on Saturn’s surface.

I pointed the scope at Mars next, but again, while a bright ruddy object, the red planet still seemed just the size of a pinhead, no matter how much magnification I attempted to throw at it. I guess I need to ask some club members for assistance with seeing well enough to find the polar ice caps. Perhaps I’m just too late in the year, since Mars now sets an hour or two after sunset and I’m looking through so much thick, dirty, hazy, humid air.

I could tell the moon had risen, but still remained low in the east, hidden behind houses and my tall pin oak in my front side yard. My observing goals for the evening included three multiple star systems. The first one I had actually observed when I first got the ETX-90 back in October 2010. The middle star of the handle of the Big Dipper is actually an optical double star, Mizar-Alcor. Terry joined me in observing this popular duo.

My second observing goal could be found in the constellation Lyra, containing the brightest star in the summer sky, Vega, and one of the three stars that form the asterism commonly referred to as the Summer Triangle. Finding Vega turned out to be easy. Correctly adjusting the movement of the telescope when aimed directly overhead, not so easy. I had to run back inside to find my red flashlight and grab my reading classes and sky atlas before attempting to star hop the very short distance from Vega to Epsilon Lyrae, also known as the Double Double. In hindsight, I also had forgotten to confirm how many degrees field of view the finderscope provided me (five degrees from the spec page of the instruction manual read this morning). Because of the light pollution around my house and the rising nearly full moon, I could only see Vega and the beta and gamma stars of Lyra. I could clearly see a triangle in the finderscope with one of the three stars Vega for sure, but which one was the Double Double? I may have observed it last night, but I’m not entirely sure. I plan to retry tonight, provided the predicted thunderstorm activity fades before ten o’clock or soon after.

My final observing objective also appeared almost directly overhead, this time in the constellation Cygnus. The head of the swan (Beta Cygni also known as Albiero) is a striking colorful double star that I easily found and observed for a few minutes. Terry also took a quick look, but opted to let the mosquitoes and chiggers feast on me instead of him. Since the moon would soon escape the defense put up by my pin oak, I asked Terry to help me carry the telescope back into the house while I held the red flashlight overhead to light our path.

I put all the eyepieces back in their cases and all the dust caps on all the openings of the telescope. I recorded two of my three observations on my Astro Quest sheets. Terry, Apollo, Lexy and I all retired to bed and left the moon to play by itself through the short summer night.

Some pros and cons about the Dobsonian telescope: I like the improved light gathering capabilities. I love the finderscope (it’s a very good quality one), but would love it more if it had a right-angle viewer. I did not like the height of the eyepiece on the side of the tube. I will need to get a portable stool to lean against. My back is still aching this morning from the constant bent over position I found myself in last night.

Overall, I enjoyed my first foray among the stars with the SkyQuest. I did not use the Intelliscope handheld device that would have assisted in identifying and locating objects. I will save that adventure for another night, possibly at a darker site.

Curious About Mars? Live Landing Event

The Astronomical Society of Kansas City will be onsite at Union Station’s Science City with telescopes and volunteers. The planetarium will air the NASA event live just after midnight.

Hope to see you there!

A Triple Line-up in Triple Digit Heat

Waxing Crescent Moon During Twilght (23 July 2012)

Despite a withering 103 degree temperature during the seven o’clock hour yesterday evening, I drug out my telescope and camera gear to the backyard in anticipation of an early evening planetary and lunar line-up. Terry grilled some chicken while I setup the scope, attached it to the portable battery and got the Autostar configured with the current date and time (almost straight up 8:00 pm). With forty minutes to go until sunset, I could clearly see the waxing crescent moon (see photo above), but the telephoto on my camera just couldn’t get me close enough to my lunar observing goal for the evening.

As I continue pursuing the Astro Quest observing award, created in 1995 by the ASKC Education Committee, I wanted to focus on the lunar section this month. The first item visible after a new moon happened to be the crater Hercules. Over the weekend, I researched all the lunar objects listed on the Astro Quest observing challenge, seeking images of the items first. I then determined I needed to find a lunar atlas. I have one for stars and deep sky objects (my handy Sky & Telescope Pocket Sky Atlas), but not a lunar one. Thanks to Google, I found the open source software called Virtual Moon Atlas, downloaded and installed it. I like it. The software makes it very easy to find features on the face of the moon and shows the current moon phase for my date/time and location.

I knew where to find the Hercules crater. Using my red dot finder scope, I honed the telescope in on the upper quadrant of the lit portion of the waxing crescent moon. Remembering to flip the image of the moon left to right in my head, I found the Hercules, and Atlas, craters easily. I spent several minutes using various eyepieces and barlows to zoom in for a closer look. I forgot to take a small portable table out with me to the backyard, so I didn’t have anything handy to take notes of my observations. I must get in the habit of doing this, if I plan to pursue other more stringent observing awards sanctioned by the Astronomical League.

I opted to mount my DSLR on the back of my telescope. I took a half dozen photos, none of which, upon downloading, were focused very well (grrrr). I selected the best of the bunch, cropped, labelled and uploaded it:

By this time, Terry had finished grilling supper, so I retired to the cool, air conditioned dining room to consume honey garlic grilled chicken and grilled Italian garlic bread with rice and Asian-style vegetables. He thoughtfully brewed some sun tea earlier in the day so I enjoyed two or three glasses of iced tea as well, knowing that I planned to return outside to the heat for more observing.

After dinner, I returned to the backyard, where I could now see Saturn, Spica and Mars, as predicted by various astronomy alerts I’d received earlier in the day. I captured the southwestern horizon at 9:30 pm in Lansing, Kansas from Astronomy magazine‘s StarDome Plus Java applet to share here. I could see another star, besides Spica, above Mars, but I’m not exactly sure which one in the constellation Virgo it might have been.

Before shutting down the telescope and returning the camera to it’s tripod, and a normal lens with a wider field of view, I turned the ETX90 towards Saturn for a quick look. I did take one photo of the ringed gas giant, which turned out better than I thought it would:

I also tried again to see the polar ice cap on Mars, but the ETX90 just couldn’t provide enough light or magnification (through the eyepieces and barlows I own) to get much bigger than the head of a pin. I could clearly tell I was not looking at a star and that the color reflected back to my eye was a ruddy orangy pink, but I could not discern any other features of the Red Planet.

The moon shone just a tad too bright to easily capture the fainter Saturn and Mars in a single photograph. Of the dozen or so shots I took with various aperture settings, shutter and film speeds, I only found one that appeared adequate:

By ten o’clock, I had all the equipment back in the air conditioned house. I had voluntarily sweated outside during triple digit heat for nearly three hours to make a few astronomical observations. I spent a few blessedly cool moments sitting in front of the fan before downloading, reviewing, editing and uploading the photos I’d taken. Soon after, I fell into bed (near eleven o’clock and two hours past my bedtime), but tossed and turned all night long. When the alarm sounded at five o’clock, I slapped snooze three times until it forced me awake at half past the hour.

Another day, a Tuesday this time, and another triple digit heat index predicted for the Heart of America. Autumn can not arrive too soon.

Teapot Steam

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:

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.

Nothin’ But Haze

And not much of it even purple.

I could easily see Venus, Jupiter and Aldebaran throughout the twenty minutes I vanely searched for the rising moon.

But I finally gave up looking for the last vestige of the waning moon with ten minutes left before sunrise.

And just before I took the camera off the tripod, I turned it north to capture some pink and purple tinged clouds.

But alas, I spied no moon amid the sea of haze washing up along the eastern horizon. Not surprising since the Kansas City area is under a heat advisory until Saturday evening (four days from now).

When I checked the star chart for the eastern horizon at moonrise later, I realized the moon wouldn’t even reach the five degree mark above the horizon before the sun rose. From the photos I took yesterday morning, I could discern the haze exceeded that height easily, which made an even thinner, dimmer crescent moon that much more difficult to find. I may have set myself an impossible task considering the amount of humidity in the atmosphere during the summer months in Kansas.

Perhaps I’ll have better luck next month capturing the elusive barest glimmer of the waning crescent moon.

Sliver of a Dying Moon

I tossed and turned most of last night, dreaming about missing the opportunity to observe nearly the last shred of the dying crescent moon. I remember waking up at two o’clock, three o’clock and again at four o’clock, and struggling to return to sleep. Getting up that early would not have helped me observe the moon, since it wouldn’t rise above the horizon until 4:46 a.m. Central.

My cell phone buzzed me with my alert at ten minutes to five o’clock. I’d been staring up at the dark ceiling of my bedroom waiting for it to officially wake me up. I grumbled my way down the stairs, with Apollo in tow, and greeted my husband and our new Rottweiler, Lexy. I only took a moment to slip on my flip-flops, grab the camera gear, my purse and the van key. I drove a block and a half up the hill to the dead end in front of City Hall and just like I did two days ago, setup my tripod in the middle of the street.

Eastern Horizon Star Chart for 5:10 am Tues 17 July 2012

I could clearly see the sliver of the waning crescent moon, just a few degrees (less than five degrees actually) above the eastern horizon. The sky appeared to be only minimally hazed. I began taking photos at 5:04 a.m. and tried various automatic settings and then revert to manually manipulating the shutter, aperture and finally the ISO, setting it to 800 (something I don’t like doing because it sacrifices pixels and detail for more light). Here is the unaltered series of photos I took, stopping at 5:13 a.m. this morning (click the image to view rest of album):

Last Sliver of Old Moon — Waning Sliver of Old Moon (click for rest of album)

I may try again tomorrow morning, but I fear the twilight will wash out any chance of seeing the extremely thin crescent of a moon less than eighteen hours away from being reborn as a new moon. Moon rise tomorrow morning occurs at 5:43 a.m. Central, but twilight begins at 4:15 a.m. Sun rise will occur at 6:08 a.m. so I would have less than a half hour to spy an even thinner crescent moon amid the growing glare of the rising sun.

I also plan to attempt to capture the first sliver of the new moon on Thursday evening, but I don’t think I will be successful. The sun sets at 8:42 p.m. and the moon sets at 8:50 p.m., just eight minutes later. The new moon occurs near midnight (about a half hour before straight up midnight) during night the 18th (tomorrow).
