It was a short night of imaging from the backyard in Oshawa tonight as increasingly thickening cloud moved in from the west. Temperature range was from +1C to +1C (20:00 to 23:30). I imaged M82
and then M81 (through cloud!) and then with only 2nd mag stars visible, I played around with a software package called APT which controls both the telescope and CCD camera, allowing such features as
auto-centering, auto-mosaicing, and automated sky surveys to be done.
There was significant dec drift tonight. I left the scope set up from last night on the ice in the backyard, and during the warm, sunny day the tripod legs melted through to the ground below,
altering the polar alignment somewhat!

| 10" f/6.3 LX200, MX916 binned 2x2 (376x291, 23.2x22.4u pixels), through cloud! I did not compensate for dec drift during this exposure... |
