Party with the Stars

ASKC Star Party Setup
ASKC Star Party Setup (Fri 20 Apr 2012)

Even though Friday dawned overcast and gloomy, by noon, I could see bits of blue among the dissolving puffs of grey and white.  I received an early confirmation e-mail from ASKC announcing the ‘go live’ time for the astronomy club’s star party at Powell Observatory in Louisburg, Kansas.  I had already invited Dad to come as my guest and not only because Terry already had plans.  The weather forecast predicted clear skies, but cold temperatures, reaching mid-40s by midnight on the observing field.

I left work at the usual time and retrieved all my riders, returning them safely home without delay.  Not even the race activities at the Kansas Speedway slowed me down when I dropped off my first rider, who lives within spitting distance of that facility.  We all could hear the cars racing around the track, not for a race, but more likely for practice or qualifying.

Peace Rose CloseupI got home and realized I had forgotten to print a map with directions from Lansing to Louisburg and wrangled Terry into printing one for me.  While I was waiting on the printout, my Dad arrived, bringing me a beautiful rose from his garden.  He placed it smack dab in the center of my table, but I didn’t notice it until I knocked over the vase with my camera bag.  Then, I mistakenly thought Terry had stolen a rose from one of our neighbors.  Dad had a hard time not laughing himself silly, especially since he tried to let Terry take the credit for the impromptu flower appearance.  I thanked Dad for the gift while I mopped up the spilled water with a spare towel.

I changed clothes, grabbed a sweater with a hood, my scarf, my gloves, a gallon of water, my water bottle, my camera bag and tripod and my purse.  Dad already had the rest of the gear in his trunk.  We rolled south out of Lansing by a quarter to six.  We stopped briefly in Bonner Springs for a quick supper and continued down K-7 to Shawnee Mission Parkway, then to I-435 and eventually US-69.  Louisburg is less than twenty miles south of Overland Park, so once we rounding the curve where I-35 crosses I-435 (where the mile markers for I-435 start at zero (0) and end at eight-three (3), we had less than a half hour of driving to reach the observatory.  We pulled into the park just a bit after seven o’clock in the evening.

The star party organizer for the ASKC was already on site.  He greeted us and we all began debating where to setup on the observing field around Powell.  He was concerned about a baseball game or practice that appeared to be occurring on a ball field just northwest of the site.  He drove over and asked the participants if they planned to turn on the field lights.  He returned to confirm the lights would be on until 9:30 p.m.  Thus, all of us decided to setup on the east side of the Powell Observatory building, letting it block the lights to help protect our night vision.

Dad and I unpacked the gear and hauled it across the observing field to a spot just southeast of the dome.  I setup my camera and tripod to take a couple of photos of the sunset.

Sunset over Powell

Friday Sunset

As predicted, the lights lit up the field, and competed with the glow of Kansas City sufficing the northern horizon. Dad and I waited patiently (him more than me) for enough stars to pop forth to attempt an alignment of the telescope. While we waited, I took a few more photos of the western horizon, mostly to capture the very bright Venus.

Venus early evening

Soon after we spotted Venus, Sirius made its appearance in the southwestern sky.  Once Arcturus crested over the trees in the northeast, we used both those stars for an alignment of the ETX-90 via the Autostar device.  We did a quick tour of the four visible planets, starting with Venus.  Even though Venus is a thinning crescent (as it moves towards us and between the Earth and the Sun), it is almost too bright to look at.  Without adding a filter to the eyepiece, I couldn’t look directly at it for more than a few seconds.  Next we caught Jupiter before it set in the west.  I spotted all four moons, but only for the first few minutes.  As it sunk closer and closer to the horizon, the haze and humidity obscured all but the planet itself from visibility.

Next we swung the telescope back to the southeast, but nearly directly overhead (about ten or eleven o’clock above us) to view Mars.  While I debated internally what higher magnification eyepiece to insert, the star party organizer joined Dad and I at our telescope.  He commented that he had owned a similar scope in years past and affirmed it was a good scope for planetary and lunar observing.  He took a quick look through the eyepiece at Mars and moved on to the next person on the field.  One of my goals for the evening was to decide if the small ETX-90 would allow me to view any deep sky objects (galaxies in particular).

Our final planetary tour stop landed on Saturn, which crested over the trees soon after we finished observing Mars.  I easily found Titan, Saturn’s largest moon, but could not discern the gap(s) between the rings, even after adding the two times Barlow to the 25mm eyepiece I prefer to use.

Orion had his left foot on the western horizon as I swung the scope back to the southwest for a quick peak at the Great Orion Nebula.  As far as I could tell, it looked similar to what I had seen from my back yard in late March.  At that time, Orion’s Sword appeared much higher in the sky and I looked through less atmosphere (but had more light pollution in Lansing).  But the combination of less light, yet more atmosphere gave me basically the same observing experience.

At this point, I took a break to spare my aching feet and sat in one of the chairs Dad had brought along.  The north wind had died off by this time, but I couldn’t seem to get my toes enough circulation.  The rest of me, my head, hands, upper body and legs, were fine.  But my toes continued to be a distraction and eventually a source of chilling pain.  I used my red flashlight to review several star charts in my pocket sky atlas, searching for a deep sky object that would be (hopefully) visible via my small scope.  I settled on the Whirlpool Galaxy found near the first star (Alkaid) in the handle of the Big Dipper.  As you can see in the chart above, just below and to the right of Alkaid is where you should find the Whirlpool Galaxy.  Even with a red dot viewfinder to help, neither Dad nor I could locate the galaxy.  It only has a magnitude of 8.4, and I fear the increasing glow from Kansas City to our north and the rising humidity as the temperature dropped to the dew point conspired against our efforts.

Before I could pick up my pocket sky atlas to find some other deep sky object to try, the star party organizer returned, asking us if we wanted to see the Leo Triplet, three galaxies visible all at the same time.  While not as clear as the photo at the left, I did see all three galaxies through his telescope in one field of view.  Amazing!  Once I returned to my scope, I directed it to find Mars (which still hovers near Leo) to confirm the alignment and then told it to find M65 (one of the two galaxies on the right hand side of the photo above.  I believe I saw a grey smudge or two, but not the third fainter elongated galaxy (on the left above).  Since Leo still appeared directly overhead, and Louisburg to the southeast does not sport nearly as much light as Kansas City to the north, I had good conditions for seeing such faint objects (magnitude 9 and 10).

At this point, I could barely stand on my aching chilled feet any longer.  I sat for a few minutes, letting my eyes wonder around the sky in hopes of seeing a few meteors.  I did see two.  I asked Dad if there was anything else he wanted to observe.  I think he returned to Saturn for a final look at the ringed giant.  After that, we dismantled the equipment and packed it back up (all in the dark with a dying red flash light).  We made several trips across the observing field to the car.

As Dad started up the car (and I turned the heat for the passenger side all the way up to red hot), the clock on the dash flashed 11:00 p.m.  We pulled out of the parking lot with only our parking lights on (to minimize light for those still observing) and stopped at McDonalds so I could buy a mocha.  All three convenience stores in Louisburg had closed (not extremely convenient for us obviously).  We retraced our route up US-69, through Overland Park, to I-435 and took Parallel Parkway back to K-7 and arrived back in Lansing just after midnight.

After this excursion, I believe I need to start saving my pennies for an upgrade.  I still plan to use the ETX-90 to observe the Transit of Venus.  The small scope is actually a boon for observing our closest star, Sol and our sister planet, Venus.  I just need the solar filter film, currently on back order, to prevent damage to my eyes and the scope.

Thanks to the Astronomical Society of Kansas City for hosting the star party.  Dad and I had an enjoyable evening.

My Mini-Messier Marathon

Venus, Jupiter and New Crescent Moon
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.

M74 spiral galaxy

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).

Andromeda Galaxy (M31) as well as M32 (another galaxy)

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.

Pleiades (M45)

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.

Beehive Cluster (M44)

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.).

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.

Post-Mercury Telescope Tuning

While I scanned the early evening skies for Mercury, Terry stayed at home, installing a secondary finder scope on my telescope.  I bought the red LED finder scope months ago because the original finder scope attached to my ETX-90 becomes unusable at near vertical viewing orientations.  Only the larger ETX-105 and ETX-125 came with a right-angle view finder.

Now all I needed to do was dial it in.  And I had at least two (if not three) easily seen objects to do it with.  I took the telescope out on the lower patio and set it up.  I opted to do an easy align this time with the Autostar handheld device and thankfully it picked Sirius as the first star to align upon.  Sirius was the first non-planet object I saw after sunset earlier in the evening during my hunt for Mercury.  After Jupiter, I saw Sirius appear about thirty minutes after sunset.  The Dog Star was clearly visible through the bare branches of my mulberry tree and the Autostar got within five degrees of it on the first try.  So, I at least had oriented the telescope to it’s home position on it’s mount correctly this time.

The second star for the easy alignment was Pollux, the twin to Castor in the constellation Gemini.  Since my house is over two stories tall and I had setup the telescope ten feet west of the tallest part of it, seeing the constellation Gemini was quite a challenge.  The two brightest stars (Castor and Pollux) had just peaked over the roof.  Then I had a moment of panic.  Which one of the two is Pollux?  I knew Castor was brighter (because it’s actually a binary or double-star that I hope to one day see separately) so I zeroed in on the less bright star.  The Autostar reported a successful alignment.  Incidentally, Castor is the ‘star of the week’ over at Earthsky.

To test how successful the alignment might or might not be, I told the Autostar to go find Venus.  Since I could clearly see Venus shining brightly next to the Moon, I knew I would be able to further tune the alignment of the telescope and the new finder scope using it as a guide star. The Autostar again got the telescope within five degrees (or less) of Venus so I proceeded to update the red LED finder scope’s focus. I had been so focused on my finder scopes that when I put my eye to the telescope’s eyepiece I realized I hadn’t even gotten one out of the case yet!  I grabbed a 26mm eyepiece and quickly focused on Venus, but it was so bright I couldn’t get a crisp clean focus.  I at least centered it in the telescope’s field of view and let the Autostar slew for a few minutes.  Venus kept creeping slowly out of the center (nothing new but something I need to look into).  Next stop, Jupiter.

What I saw last night through my telescope looked very much like this photo.

Again, the Autostar got close, but not quite.  I’m beginning to think I need to recalibrate and retrain the drives in the ETX-90 mount.  Jupiter in all it’s glory with four moons visible (two on either side).  I grabbed Terry out of the band room to take a quick look, but he retreated back inside because of the cold.  I hardly noticed it, having stood outside during sunset for over and hour and now observing from the backyard in just a t-shirt and jeans (the house provided a substantial windbreak).

At this point, I was happy with the installation, configuration and usefulness of the new red LED finder scope.  What could I attempt observing before packing up everything and returning it to the band room?  Ah!  Something in Orion.  Thankfully, Orion appeared high in the sky, almost due south (just a bit to the east).  Since I suffer from an extreme light pollution epidemic in Lansing, the higher up an object, the better to minimize the amount of light and atmosphere I need to peer through.  Having a clear cold night to make the air dense also helps.  I searched the Autostar’s object database and found the Great Orion Nebula.  Fetch! I said and off the telescope went.

The telescope stopped in the general vicinity of the belt of Orion.  I didn’t think that was the exact location of the Orion Nebula, so I grabbed my Sky & Telescope Pocket Star Atlas and confirmed the location as being in the sword, not the belt.  Using both finder scopes, I slowly got the telescope oriented on the objects in the sword.  Using the eyepiece, I slowly scanned the much smaller field of view and saw a grey cloud like smudge pass by.  I stopped.  I returned to the smudge.  This must be it!  I put in a stronger magnification eyepiece and spent several minutes taking in the sights of a nebula. Only long exposures with very sensitive camera equipment equatorially mounted … or the Hubble Space Telescope in orbit (outside of our dirty atmosphere) … can produce stunning color images like this one:

In one of the most detailed astronomical images ever produced, NASA/ESA's Hubble Space Telescope captured an unprecedented look at the Orion Nebula. ... This extensive study took 105 Hubble orbits to complete. All imaging instruments aboard the telescope were used simultaneously to study Orion. The Advanced Camera mosaic covers approximately the apparent angular size of the full moon.

I hope it was the Orion Nebula.  I am almost convinced it was, but since my telescope is a reflector (not a refractor), the image I view in the eyepiece is not only upside down, but reversed right to left, and almost always black-and-white (or gray).   When I compare what I see to a star atlas, I have to do mental spatial gymnastics on the fly.  I did get Terry to come out one more time and view the smudge that was a nebula before packing up the telescope and putting astronomy to bed for the night.

I woke up before sunrise this morning (no surprise … I always do that with or without an alarm).  I fed the dogs and when I let them out the back patio door, I noticed to bright objects in the western sky.  They both had to be Saturn and Mars.  I went to Terry’s computer and logged in to my Astronomy.com account (since I subscribe to the electronic edition of Astronomy on my Nook Color, I get ‘extras’ on their website).  Using their StarDomePlus Java application, I confirmed the contents of the sky at that exact moment from my location in Lansing.  Yes!  Mars was the bright spot in the western sky and Saturn appeared just up and to the southwest of it.  If only I had gotten up an hour or so earlier, I could have set up the telescope (again) and looked at Mars and Saturn both.  I think I just found my next astronomical hunting expedition.

Tonight’s highlights include, for early evening viewing, more of the Moon, Jupiter and Venus (and Mercury if I wanted to leave my backyard, but I’ll pass on that tonight).  For a headsup on what to expect in the coming week, visit Sky & Telescope‘s This Week At a Glance site.
