I imaged from the back yard in Oshawa tonight. Temperature range was from +10C to +7C (session from 21:00 to 05:00).

I imaged M51,63,3,13, and NGC6229 using the MX5C. The seeing was not very good after about 02:00, so I'll definitely re-do tonight's M13 image (it still looks pretty good though).

I notice now that the Coma Berenices asterism is almost completely undetectable now (even with averted vision) due to light pollution. The skies in Oshawa are definitely much worse now than just a few years ago; the sky in the NE direction has brightened most of all.
