Astrotrac M31 & NGC6888

After quite a long break from imaging and a lot of fiddling I have dusted off the camera and AstroTrac mount.  Last night the conditions over Southampton were not too bad with only occasional broken cloud.  The setup for the night was my modified 350D and 500mm f/8 Catadioptric Tamron SP lens, mounted on the TT320X-AG mount.  The first of these images is NGC6888 (Crescent Nebula) consisting of  12 x 5min subs unguided.

Becuase of the amount of realignment required to get M31 (Andromeda Galaxy) on the sensor I had to drop the exposure time to 4mins as I had managed to move the polar alignment out by a tiny bit but I am pretty happy with the results.  This was 13 x 4min subs with dark, flat and bias frames. The focus is a tad out but I figured that this was pretty good considering it was my first night attempting to use this camera lens to do some astrophotography.
