40x 30sec exposures, ISO800, Canon EOS1100D with Sigma 70-300mm lens (at 300mm), f/5.6.  11 darks, 20 flats, 20 bias.  Stacked in DSS, processed in Photoshop.

Not perfect by any means.  I wanted to take at least double the number of exposures but the clouds came in to ruin that plan!  But even so, I'm quite happy with the result.  Far better than my previous attempts which were very short exposures on an alt-az mount:

First attempt was taken in April and was 11x 4 second images at ISO6400, 200mm lens.

This one was taken on 22nd November, again on Alt-Az mount with very short exposures, but a lot of them.
