This was taken on Friday night with my Canon 550d. I grabbed my Saxon 4 inch f5 refractor and placed it on the Canon using it like a 500mm prime telephoto lens. No tripod, just hand held, which took some effort as the tube is quite heavy and holding it in the left hand while focusing the rack and pinion with the right hand was tricky. I had to use a shutter speed of 1/2000 of a second to reduce camera shake.
