Big night tonight! Session was from 16:45 to 06:00. The focus point on my TCFS has wandered up to around 4300 now. We're now getting into the cold winter weather with lows around -10C. There was a 12C temperature difference between the observatory and the attic at one point tonight (-7C in oby, +5C in attic). Definitely need to fit the rest of the attic with vapour barrier to make the attic colder! The dome does get a little frosty on the inside these days.

When I tried to go to XY Psc, the moon (just 25deg away) interfered too much as shown in the image below. Ideally, I need to be at least 45deg away from the moon to avoid moonglow.
