Relatively brief night tonight. It's nice and cool, but transparency isn't the greatest.
I started the evening (around 11p) with a look at Jupiter, and took some vid of a moon (Europa?) just as it was entering Jupiter's disk. I'll have to process it and see how it came out.
I spent about another hour with the horsehead region, and guiding (using PHD) was fine for the first hour when running 5min exposures, but I set up another hour worth of 10min exposures, and guiding got wonky again. I took a screenshot of my graph in PHD so I intend to post it to the AstroPhysics list tomorrow to see if anyone can give me any ideas.
Got a bit done, and was a pleasant enough evening.
