Our overlooked galactic neighbour

M33, or the Pinwheel galaxy is only slightly further away than the Great Andromeda galaxy (2½ million light years!), but it can only just be seen with the naked eye from a very dark site, on a good night. I got this shot yesterday at the equinox sky camp in North Norfolk through the 400mm telephoto lens, and pushed the contrast a lot. It has a very low surface brightness as it is almost face-on to us, which makes it difficult to see well. I need more exposure time with this one, but I will have to sort out my scope's tracking motor and find some very dark skies to some good shots.
