I imaged from Oshawa tonight with the MX9, despite the almost full moon! Temperature range was from +8C to +3C (19:30 to 04:30). I imaged M53 and then decided to try going after some asteroids -- something I've never done with a CCD before! It turned out to be so fun, I didn't get around to imaging M3 later in the night!

The highlight (or should I say lowlight) of the night was imaging 315 Constantia at magnitude 16½! (At full moon from the city in 30 seconds no less!)

I also imaged Pluto just for the heck of it (something else I've never done before!). If I can image Pluto on two different nights in the same field, I can put together a nice little animation.

I imaged the following 8 asteroids:

# Name Mag
6 Hebe 9.6
13 Egeria 9.8
145 Adeona 11.3
157 Dejanira 13.8
197 Arete 13.1
264 Libussa 12.7
293 Brasilia 13.5
315 Constantia 16.4

Animations are shown below for two of them.
