I thought I would have a go at taking pictures through my small WO Megrez 72 with my new Canon 7D. I was surprised at the results. This was taken using a Skywatcher field flattener and is a crop of the full frame. The full frame was pretty sharp to the edge. The scope and camera were supported on a AZ4 mount. A 1/400 sec exposure at ISO 100
