I imaged from the back yard in Oshawa tonight. Temperature range was from +10C to +3C (session from 21:00 to 05:00). Tonight's skies were the darkest and most transparent I've seen this year (I was able to see the Teapot of Sagittarius even with the moon up!). Around 02:00 easterly breezes started to jiggle the scope, so I had to put up my makeshift shelter again just like last night.

I imaged NGC4565, M64, NGC5907 and M13.

NGC 4565 50 minutes (100 x 30s)
NGC 4565, 50 minutes
NGC 4565 (10" f/6.3 LX200).

M 64 45 minutes (90 x 30s)
M 64, 45 minutes
M 64 (10" f/6.3 LX200); 30 iterations of Lucy-Richardson deconvolution.

NGC 5907 47½ minutes (95 x 30s)
NGC 5907, 47.5 minutes at f/6.3
NGC 5907 (10" f/6.3 LX200).

M 13 21½ minutes (43 x 30s)
M 13, 21.5 minutes at f/6.3
M 13 (10" f/6.3 LX200).
