I imaged from the backyard in Oshawa tonight. Temperature range was from +7C to 0C (session from 20:30 to 03:15). After polar aligning, I did some visual variable star observing for the first hour. Then I imaged NGC 6946, NGC 7662, and NGC891 (stopping at 03:15 when cloud rolled over the whole sky).

NGC 6946 58 minutes (58 x 60s)
NGC 6946, 58 minutes at f/6.3
NGC 6946 (10" f/6.3 LX200).

NGC 7662 6½ minutes (13 x 30s)
NGC 7662, 6.5 minutes at f/6.3
The Blue Snowball Nebula -- NGC 7662 (10" f/6.3 LX200).

NGC 891 66 minutes (132 x 30s)
NGC 891, 66 minutes at f/6.3
