Another big (and cold) night! Session was from 17:00 to 06:30. I defrosted the dome today, but at dawn the shutters wouldn't close! I think there was too much frost on the contacts so no power could get to the motors.

UMO @ omicron Aurigae 2 sec
UMO in o Aur field
Scope: 10" f/6.3 LX200 | Camera: MX916 binned 2x2.

Note on time: I set my computer's clock with NIST at the start of the session. When I checked again on the afternoon of Dec 5 at 13:38, NIST reported "Local clock - NIST = 1.460 seconds."
