Triangulum is not one of the easiest seen constellations, but at least it does look like its name suggests it should. Adjoining Andromeda, Triangulum is home to the great galaxy M33. M33 is a companion to M31 in next door Andromeda and one of our Local Group. It is hard to see visually due to its size and low surface brightness, but can be seen as a faint smudge in this image. The bright yellow star well above M33 is Beta Andromeda, with M31 just out of shot. Above Beta Triangulum is NGC752, an open cluster.
