Stellafane 2013

Maybe it's because it's like 10°F outside and I'm longing for some warmer weather - but it occurred to me that I never posted any of my images or experiences at this summer's Stellafane convention. So, in the spirit of better late than never...!
It had been a decade since my last trip north to the Stellafane convention, and with this year's event running from Aug 8th - 11th in close approximation with the Perseids I decided to pay a visit. I had originally planned to take off on that Thursday morning for the approximately 7 hour trip to Springfield, Vermont but, to be honest, I am indeed a fair weather camper. The forecast was not just for rain but for heavy rain, so I opted to use Thursday to tweak my yard sale refractor for some piggy back photography. Friday I was on the road by 5: 30 a.m. and arrived at Breezy Hill by early afternoon.
As I expected all the prime spots were taken by those willing to put up with the rain on Thursday, but the convention grounds are pretty large and I headed for the southeast corner where I've camped many times previously. While little had changed to the topography of the place I was a bit dismayed to see the field pretty much designated for vehicle parking, with "No Camping" and "No Observing" signs prominently posted. In the past we would park there and set up the tent on the perimeter of the field, pulling the scope out of the car in the evening for observing car side.

Friday was drizzly but towards evening there were signs that the weather might break. Sure enough around midnight the sucker holes blossomed into major openings. I pulled my 15x70 Oberwerks from the car along with my tripod and Canon Rebel T3. A major objective for me on the trip was to begin to learn how to use the DSLR for astrophotography (don't get me started about how taking shots with a SLR & film was, in many ways, a simpler process!). Happily the initial tripod shots were a success, so I turned in around 1 for some sleep.
Saturday morning dawned with a crisp blue sky and the promise of a dynamite night ahead of us. I wandered up to the swap tables, always an interesting assortment of items there, from the quirky to the classic. As my stomach began growling I took the car and drove the short jaunt into town where the local Royal Diner served up a generous portion of blueberry pancakes with real Vermont maple syrup. Hey Guy Fieri - you need to check out this place!
The rest of Saturday was spent enjoying the talents of my fellow astronomers. A good walk over to the pink club house to look over the telescope entries was fun.
Gorgeous view atop Breezy Hill
I am always amazed at the craftsmanship and sometimes whimsical approach that various contestants apply to their entries. There were also talks given in their large pavilion throughout the afternoon. Phil Harrington gave a great overview of building one's own backyard observatory, and Richard Jakiel did a survey of lunar features that are readily imaged with backyard telescope and webcam.
Saturday evening started with the featured program and keynote address. The raffle was drawn for some very nice gifts that had been donated to the convention, and then John Bortle presented the "Shadowgram" in which he reminisced about the history of Stellafane and some of the luminaries who have attended. The keynote was provided by Brother Guy Consolmagno of the Vatican Observatory on the topic of comets. By the time he concluded the skies were clear, dark, and enticing.
Lyra and Hercules
Feeling roguish I pulled my 60mm refractor and DSLR and set up beside my car (I figured if anyone objected then I could pop it back in within a minute). I spent until about 2 a.m. photographing the sky and seeing how well my piggy back tracking setup would work. I also glimpsed multiple Perseids streaking across the sky, but none on any of my shots. Probably the most memorable view was M31 (and M110) in the Oberwerks - awesome does not even begin to describe how impressive that galaxy looks set amid a dark sky and these binoculars. The size of the galaxy is really brought home with that view, and the clarity in the optics makes me think I could even make out a bit of the dark lane in Andromeda. The only drawback to the evening were the antics of some others on the field. I know it was not set aside as an observing area and therefore have no right to complain, but playing with green laser pointers, packing your car at 11:30 p.m. with the dome light on, and cavalier use of unshielded flashlights was really disappointing to see.
Cassiopeia and the Winter Milky Way
Overall I would have to say that this year's Stellafane convention was a great success. It was (as usual) very well organized, had a great set of speakers, interesting telescopes on the field, and clear skies that showed of a limiting magnitude of 6 to even my aging eyes (with glasses)! What more could you want in an astronomy event?

Jupiter Under A Wolf Moon

You have to love the Indian names for the various full moons throughout the year (so much better than the inane "Super Moon" hype we have had the last few years when full moon coincides with perigee). So this week was the Full Wolf Moon1 - and while you might expect evening temps in the 20s or lower under a Moon with such a chill name, we actually caught a break. Temperatures were a tad above freezing and a bit of humidity in the air offered some stability to the atmosphere.
When I am on the fence about setting up the equipment for a session I usually do a quick check on two things:
  1. Will the Great Red Spot be visible?
  2. Are the Galilean moons doing anything noteworthy?
Well fortunately the GRS was due to make an appearance, transiting a little after 8:30 local time, so even though Jupiter can be awesome with unpredicted features on any night, I knew that on this night I could catch GRS for the first time in 2014.
The Wolf Moon trailed Jupiter in the eastern sky as I set up the scope, camera, and laptop. It served as a pretty good target for fine tuning my focus, although I prefer a little more terminator to work with. For whatever reason it took a solid half hour to get everything set and ready to roll, hands growing colder as I tweaked and calibrated to the best of my ability. Finally a little after 9 I started capturing, and I could tell right away on the screen that the Great Red Spot was visible and clearly past central meridian.
As usual the southern edge of the SEB preceding the GRS was the most intense cloud feature. The SEB itself appears bifurcated pretty much throughout this side. The NEB has some hints of a couple of festoons, and the NTB seems to be a bit more compact and intense longitudinally near the meridian. All in all a nice start to 2014!
