M33 is one of the great pities of the night sky. In Triangulum, it is one of our Local Group, along with M31 and its companions. It is a beautiful face on spiral, but of such size and low surface brightness that it is very difficult to see in a telescope and also hard to photograph. It is claimed to be visible in binoculars given a clear enough sky. If it was as bright as M31 it really would be a deep sky gem.
