Had a pretty good night last night. Seeing started out well, 7/10, but it and the transparency deteriorated by midnight. It was very warm during the night, so it's possible I had some boundary layer issues, though I didn't try the fan -- I should next time out. I found with the lists I'm using, that I can mostly stay on the ladder without moving too much, though I do start to fall behind in sidereal time and need to adjust every hour or so. I still need to get better pointing accuracy. I did Vega and Arcturus as alignment stars and that seemed ok, but there's enough error even with local sync that I need to find the stars with the charts sometimes -- and even then the charts don't agree with what I see in the eyepiece. The computer is very laggy, and it might be worth investing in a new one. Observed until midnight.
