I only caught Venus and Jupiter twice this week with my camera. Between a day trip to Chicago and occasional sporadic thunderstorms, I only caught them Monday and Thursday nights.
The best shot from Monday night included this closeup of the Moon and Venus:
The only other remotely astronomical activity I did this week involved a short trip across the Missouri River to Parkville. My dad and I drove over to window shop at the HMS Beagle store. Due to a wrenched back, I had to cut our visit short, but I did purchase a nearly waterproof “Guide to the Stars” star-wheel for Terry to use when he visits the hot tub after midnight. I also picked up a laminated map of the moon, which I left with dad, along with my scope, at his house.
I spent a lazy Sunday writing blog entries and emails, reading an ebook and watching the best bits of an old movie (Hatari! from 1962). I kept one eye on the clock and the other one on the sun because I did not want to miss the opportunity to photograph the conjunction between Jupiter and the Crescent Moon (the moon passed within three degrees of Jupiter last night). I had witnessed a similar conjunction last month when I went hunting for Mercury and caught it.
I had read earlier in the day that you can sometimes see Jupiter before the sun sets with your naked eye. I could easily see the moon and Venus before sunset, but try as I might I could not discern Jupiter amidst the twilight glare, even though the skies were exceptionally clear, free of clouds and haze and the wind seemed calm or non-existent. I switched my camera from it’s normal lens to the telephoto and took closeups of the moon in the hopes that I would later be able to find Jupiter once I downloaded the photos. I proved that theory this morning with the following photo:
First Glimpse of Jupiter and the crescent Moon (bisected by a power line)
I spent the next hour taking the occasional snapshot of the triangular conjunction and several planes that flew near or through the area. To view most of the photos (the ones worthy of uploading) in an album (or a slideshow), click on this link.
I packed up the camera and tripod at about half past eight and traipsed back inside. I returned to my library and finished my ebook just a minute shy of ten o’clock. I needed to charge my Nook Color, which required descending downstairs again. Since I was up and halfway to the band room, I decided to drag the camera and tripod back outside in an attempt to photograph the constellation Leo and the visiting Mars. I had to switch back to the normal lens as I could not get the entire constellation in the field of view available through the telephoto. I took three or four snapshots of Leo and Mars, but I could not see the stars very well through the viewfinder or the preview display on the back of the camera. I just had to cross my fingers and hope that my efforts had captured enough of the stars to clearly see the outline of Leo. The best of the photos turned out to be the three second exposure shown here:

This is the same photograph edited to add lines to outline Leo and a label for Mars:
My dad and I attended the March 2012 general meeting of the Astronomical Society of Kansas City last night. We arrived an hour early to attend separate meetings. Dad sat in on the Astro 101 class. March’s topic happened to be astrology of all things. Here’s the blurb from the ASKC’s web site explaining it:
For March, the topic is: Astrology — that’s stargazing, right? So, do you do horoscopes? Say, what’s your sign?” Wha???? Huh???
Sooner or later you, as an amateur astronomer, will run into something like the comments above from a friend, co-worker, relative or casual acquaintance who thoroughly confuses astrology and astronomy. Our own “Madame Ursula” (aka Jackie Beucher) will enlighten us all on the Zodiac, sun signs and what it doesn’t mean. Come join us at the March 24th Astro 101 session.
I attended a brain storming session for the teams responsible for administering the public nights at the Powell Observatory. Lots of good ideas were presented.
Dad and I reunited just before seven o’clock and chatted briefly with a couple we’ve known for years (and who happen to live in Leavenworth County as well). We seated ourselves with a couple of minutes to spare.
After some brief comments from the President on the ongoing Messier Marathon down at the dark site and an exercise in democracy (another paper ballot vote on a by-laws change), the Education Director took the stage and presented “April 2012 Sky Events” which actually spanned the next several months.
Transit of Venus (2004 - Wikipedia)
The highlight of his presentation proved to be the once-in-a-lifetime chance to observe the Transit of Venus on June 5th. I took mental notes, realizing I would need to purchase or engineer a solar filter for my ETX-90 in order to observe the transit. I only get one shot at this, because the next time this happens, in December 2117, I will be long gone. This morning, while researching solar filters, I found a helpful web site on safe solar viewing which I wanted to share with all of you. You don’t need a telescope to observe, but please take precautions (to avoid damaging your eyes) if you plan to observe any solar events (eclipses, sunspots, transits, etc.).
The main event of the March general meeting culminated in a presentation by Fred Bruenjes. His riveting account of discovering, just last month, Comet/2012 C2 (Bruenjes) impressed all of the audience. Follow this link for a similar recitation via Fred’s own web site, MoonGlow.net. Fred plans to continue comet hunting because, in his own words, the one he discovered was ‘defective.’ I disagree. It wasn’t defective, just unique. The most unusual feature of his comet is its orbit, which goes in the opposite direction of all the other solar system objects (planets, asteroids and comets).
On the ride home, I regretted leaving my camera and tripod lounging in the band room because I missed a stellar (pardon the pun) opportunity to photograph the crescent moon, Jupiter and Venus. I will get another chance this evening, when the moon is slightly larger and much closer to Jupiter. Click here to see my photograph of the three objects taken early Friday evening.
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 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.).
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.
For the past week, weather permitting, I took a series of photographs from my backyard during the early evening. I tried to get the tripod and camera positioned in roughly the same spot. I also tried to remember to take the photos at about the same time, during the eight o’clock hour. I believe I was more or less successful. The following are the best of the bunch in the progression of the mid-March 2012 Venus Jupiter Conjunction:

I loved this film. I would even go so far to say I loved it better than the original book the screenplay was adapted from, A Princess of Mars by Edgar Rice Burroughs. As soon as the BluRay for John Carter is released, I am buying it. That’s saying something, since I haven’t actually purchased a DVD or BluRay for myself in years (as a Netflix subscriber, why would I?). The last film worthy of that feat (but only on the discount table because I’m so cheap) would have been Live Free or Die Hard, but I didn’t get the chance since my daughter gifted it to me for my birthday last year. I plan to add John Carter to my permanent collection, shelving it next to my special collector’s editions of Star Wars and The Lord of the Rings.
Go see John Carter. Now. Don’t wait.
You don’t need to be a fan of science fiction or epic fantasy to appreciate a good tale well told, one that leaves you shouting for more.

Oh, and I almost forgot. I liked the musical score as well, which came as no surprise when the credits started rolling and listed Michael Giacchino as the composer. His work on The Incredibles impressed me so much I bought the soundtrack CD (another thing I haven’t done since the days of Star Wars).
I can’t wait until this weekend to see John Carter at the theater. I would have bought my tickets over lunch except my favorite theater has not yet listed showtimes for this weekend. I convinced my uncle to venture forth as well this weekend. But the real icing on the cake came with the short note he sent me this morning proclaiming his success in finding A Princess of Mars by Edgar Rice Burroughs at Project Gutenberg and getting it downloaded to his Nook Color.
My local favorite library posted a cool YouTube video via their Facebook and Twitter feeds that I’d like to share here, prefaced by their blurb:
Do you know who created Tarzan and John Carter of Mars 100 years ago this spring? Check out this video preview of an upcoming event featuring author, critic & broadcaster John Tibbetts celebrating the legacy of an American cult icon…
And thanks to an update from Sky & Telescope‘s Facebook feed, I learned that “Mars is at its closest to Earth for this apparition: 100.8 million km (62.6 million miles). Mars appears 13.9 arcseconds wide, compared to the 24″ or 25″ it reaches during its closet swing-bys. The last time that happened was in 2003; the next will be in 2018.” I saw Mars shining brightly this morning in the west before the sun arose, when I let the dogs out after they ate their breakfast.
I valiantly kept myself awake past my pumpkin transformation time (usually half past nine o’clock on weeknights), reading an ebook on my Nook Color while Terry dozed through the UFC fights. When I finally got within twenty pages of the end of my book, I put the ereader aside and checked the position of Mars from my front porch. The waxing moon hung at about the one o’clock position in the sky almost hidden behind my house and Mars shown redly at about the ten o’clock position. I decided to setup the telescope in my driveway, even though all the street lights and house lights concentrated their glows more intensely on the east side of my property.
I opened the garage door and began transferring the telescope and accessories from the band room (behind the garage on the west side of the house) through the garage to the driveway. I had put on a sweater but only had flip-flops on my feet (something I would come to regret an hour or so later).
In setting up my telescope, I made an error in the home position and failed two attempts at an easy alignment. When I finally realized my mistake, after having run the motors up to and beyond the stops twice, I tried a third time, but the Autostar control device disconnected itself from the telescope and reset itself twice. I gave up and finally just pointed the scope at Mars, shining brightly and sanguinely from the constellation Leo.
Two of the stars selected by the Autostar alignment program included Sirius, in the constellation Canis Major, and Capella, in the constellation Auriga, and both of these stars could be found in the Winter Circle. The waxing moon enjoyed center-stage in the Winter Circle on a cold clear late winter night.
Once I got Mars in my sights, I tried various barlows and eyepieces, but could never quite get a good focus on it. I could dimly and vaguely see the polar ice cap and Mars definitely had an orange-ish and pink-ish cast to it.
By this time, I could barely feel my toes, but I didn’t want to stop observing, so I turned the telescope farther eastward, looking for Saturn. I found Spica in the constellation Virgo. Saturn is just a short hop to the left of Spica. I clearly saw the rings, but did not take the time to look for Titan or any of Saturn’s other moons. I wanted to get my feet warmed up, so I shutdown the telescope, packed everything up and transported it back to the band room.
I may repeat this entire process tonight, but from a different location. I will take a nap this afternoon to allow me to stay up past my pumpkin transformation point.
Oh, and I did get my feet warmed back up while finishing the last twenty pages of my ebook.
Much of my March will revolve around Mars. For example, this Saturday, March 3rd, according to Sky & Telescope‘s ‘This Week’s Sky at a Glance‘ (both for this past week and the one ahead), Mars shines highest in the south, in the sharpest telescopic view, around midnight.
Mars is at opposition, appearing opposite the Sun in Earth’s sky. This is the most distant opposition of Mars in its 15-year cycle of oppositions near and far, so the planet appears only 13.9 arcseconds wide. At its next time around in April 2014, Mars will reach a diameter of 15.2″.
My goal is to stay up late enough on Saturday night to allow the moon to set (or almost set) and Mars to be either directly overhead or just over the top and falling towards the western horizon. That will optimize my viewing, reducing the amount of atmosphere I must look through and minimizing the effect of the light pollution in my area.
For this first weekend of March, I think I will limit myself to my own backyard. I did receive the new power cord I ordered for the ETX-90 yesterday, so I will test that out tonight with the portable battery pack my father reconditioned and gifted to me. The following weekend will present more difficulties observing Mars since the Full Moon will be two days old on Saturday the 10th.
Just a day or two after the vernal equinox I hope to join other members of the Astronomical Society of Kansas City (ASKC) in the annual Messier Marathon – an attempt to find as many Messier Objects as possible during one night. Since the new moon occurs just two days after the equinox, my only concern would be clouds to obscure an otherwise perfect dark night sky. I don’t plan on needing a tent, since I wouldn’t be sleeping until the sun broke over the eastern horizon anyway. I will really regret giving up drinking tea and coffee (or any kind of beverage except water) for Lent during that long night. I just hope the excitement of discovery will keep me awake.
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.
ETX-90 with new red LED finder scope installed
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.
