I imaged from the backyard in Oshawa tonight. Temperature range was from +11C to +8C (session from 01:00 to 06:00). I did some visual variable star observing during which time the wind died down. Just before 4am I started gearing up for a CCD shot. That's when some breezes started up, so I set up my ladder and blanket arrangement to shelter the scope. I was hoping to get 30 minutes on the Crab Nebula, but only 27/60 shots were not trailed. Hopefully I can get another 15 minutes or so later this week to complete the shot.

M 1 13½ minutes (27 x 30s)
M 1, 13.5 minutes at f/6.3
M 1 (10" f/6.3 LX200).
