I went galaxy hunting the other night. This is a closer up version of the pinwheel galaxy or M33, shown below when I tested my 400mm camera lens. I got 6 30 second pictures on the 20" scope, all were very trailed in different ways, but I detrailed them all seperately, painstakingly! Then I stacked them, hoping that the trail artefacts left over would somehow "average out". Anyway there was a lot of red background noise, so I had to make the colour a bit bluish for the galaxy to stand out - as its light is very spread out. Good result I think?
