The awesomely delayed New Year’s post

March 27, 2011

The year is almost exactly one fourth gone, so this is more than a bit late. But 2010 was a transformative year in my astronomical career, and I wanted to explain why and how, and to assess how I did on my astronomical New Year’s resolutions.

My first resolution was, “I resolve to spend less time mooning over the stuff I want, and more time using the stuff I have.

I’m calling this one a mixed success. On one hand,  I did a LOT more observing in 2010 than in any previous year. Not in terms of sessions–I did 95 in 2010, versus 110 in 2009–but in terms of time spent and objects observed. In 2009 I probably observed a few dozen things; in 2010 I saw more than 200, the great majority of which were new to me.

I got off to a strong start, taking advantage of the good sky transparency after winter and spring rains to do a lot of observing from my driveway, especially with binoculars. I completed the Binocular Messier Club by mid-February, and did most of the observations for the Messier Club and Deep Sky Binocular Club between January and March.

Crucially, I finally started getting out to dark sites on  a regular basis. I first started observing in October, 2007, but I had only been on one dark-sky observing trip before last year. Two factors played a role here.

The first was getting up to Mount Baldy with a friend from the PVAA in the fall of 2009 to try to catch the impact of the LCROSS mission on the moon. We didn’t see the impact fireball–no one on Earth did, not directly, although the LCROSS probe sent back good pictures and data showing that yes, water ice is indeed present in the craters at the lunar poles. What turned out to be more important for me was the revelation of how much more I could see under those darker skies, and the shedload of deep-sky objects I was able to observe that night, mostly with 15×70 binoculars. That night was also a big step forward for me because it was the first time I had taken out my Pocket Sky Atlas and used it to really cruise the skies, rapidly finding my way to new objects that I’d never seen before. So come the beginning of 2010, I knew that quite dark skies were available close by, I had the motivation to get out to them, and I was learning the skills I’d need to take advantage of them.

The other big factor is that my son, London, was 5, so he was both more adventurous than he had been, and also required quite a bit less minding. It was time to go camping. My trips to the Salton Sea in January, February, and March of 2010 were solo efforts, although I met up with at least one other PVAA member each time. But almost all of my later dark-sky outings were camping trips. We went to Owl Canyon in June and September (London stayed with Vicki in a hotel room on the latter trip), Joshua Tree Lake and Afton Canyon in October, and the All-Arizona Star Party in November. And we’ve already been out once this year, to the Salton Sea again (the Salton Sea is more southerly and lower in elevation than the high-desert observing spots I’ve been to, so it’s warmer overnight during the winter months). The impact of these dark-sky trips is hard to describe. I have had experiences out under those dark skies that would simply have been impossible anywhere else. I don’t think it’s going to far to say that they have not only changed me as an astronomer but as a human being.

I mentioned that my resolution observe more and obsess about gear less was only a mixed success. I did spend less time mooning over telescope  catalogs and telescope vendors’ websites, and more time at the eyepiece, so that part was okay. But I also turned over almost my entire telescope collection, selling off old stuff and trying out new stuff in the quest for the perfect lineup. I think every single telescope I own right now was purchased in 2010, except for the Astroscan, which is really London’s. I learned some valuable things along the way. I know now that a 10″ dob is as much big iron as I need for at least the near future. I found my ultimate no-excuses travel telescope. And I got a couple of nice mid-sized telescopes, both of which turn in good images without breaking either my back or my bank account. I’m not done buying telescopes–I would like to get a 5″-6″ SCT or Mak to have something more portable than my current mid-sized scopes but equally capable–but I think I’m  converging on the ideal scope collection for my observing interests. It wouldn’t hurt me to concentrate on getting some non-telescopic gear, like a light-pollution filter and some better eyepieces.

My other resolution for 2010 was, “I resolve to complete the Astronomical League’s Galileo Club, Lunar II Club, and Messier Club.” This one was also a mixed success. As I’ve reported (more than once, and if you’re tired of hearing about it, I don’t blame you), I did complete the requirements for several of the Astronomical League’s observing clubs, just not all of the ones I resolved to finish. This was mainly caused by the big shift in my observing habits mentioned above. Prior to 2010, essentially all of my observing was done from home, under light pollution, and so I naturally gravitated to projects that were easy to complete under those conditions. Hence the interest in the Lunar II and Galileo clubs (although I was also interested in the latter simply because Galileo was The Man). Last year my interest shifted to the deep sky (i.e., objects beyond the solar system: nebulae, star clusters, and galaxies) in a big way, and all of the clubs I completed in 2010 are deep-sky programs.

So what about observing programs for this year? I’m only 9 objects away from completing the Urban Club, although I let a few of them slip too near the sun so I won’t be able to put that one to bed until a few months from now, when they’ve escaped (or, more accurately, when our orbit around the sun has moved the sun’s apparent position against the background stars). I should do more on the Double Star Club–like the moon and planets, double stars are little affected by light pollution, so those will give me something to chase on the nights when there’s too much humidity, smog, or dust to go after faint fuzzies.

NGC 4038 and 4039, a pair of colliding galaxies popularly known as the Antennae. Part of the Herschel 400.

But those are really incidental. My big observing push for the foreseeable future is the Herschel 400, a list of 400 of the best out of the more than 2500 deep-sky objects cataloged by William Herschel. It’s deliberately intended as a follow-on to the Messier Club, to help observers further develop their skills and see more of what’s out there. I started on it last fall, not in earnest but as a way to pad out my sessions as I finished up the Messier and Caldwell lists. Quite a few of the objects for the other deep-sky clubs are drawn from the Herschel 400, so between having completed a few of those and having started on the Herschels last fall, I’ve got almost a quarter of them–95 out of 400–logged already. Sounds like quite a bit of progress, but most of those 95 were chosen for other clubs because they’re among the best and brightest, so I’m afraid many of the gems are already logged and the remaining 305 are going to be mostly true faint fuzzies. Still, one never knows until one looks, and even my limited exploration of the rest of the Herschels has turned up some surprisingly beautiful objects.

So, I’m going to work on the Herschel 400, but I’m not going to commit to finishing it this year. I had a lot of fun last year but almost suffered from observing program burnout. This year I’m going to take a more relaxed pace. If I finish a few things along the way, great, but I’m not going to push myself to do it.

Still, I am not without goals, and even though three months have passed I’m going to make some astronomical resolutions for 2011 (only having 9 months to work on them ought to add spice).

Resolution #1: I resolve to not give up on observing from home.

All the dark sky trips in 2010 were great, but after a strong first quarter I did a lot less observing from home after March. There is a danger here, of developing the attitude that it’s not worth going out unless I can be under inky-black skies. The truth is that there is a lot of great observing to be had in town, especially if one chooses the right targets and the right times to observe. As I ought to know, since I got so much deep-sky work done from my driveway last year, mostly with very modest instruments. So I am going to try to get in at least one or two serious observing sessions from home every month, light pollution be damned.

Resolution #2: I resolve to spend more time on every object that I observe.

This one is also a reaction to my experiences last year. Some people dismiss observing programs as a list-checking exercise that corrodes the relaxed, contemplative side of observing. I don’t think that’s universally true–I always take at least a couple of minutes on each object to jot down my observations and impressions–but I would be lying if I denied that that danger exists. So one of my goals for 2011 is to improve the quality of my observations, and not to worry about their quantity.

And…that’s it. That’s all I really want for this year. I certainly grew as an amateur astronomer in 2010. In 2011, I want to mature as an observer.

I’ll let you know how it goes.
