M33, "The Pinwheel Galaxy", is a very distant and large spiral galaxy, some 3.6 million light years away with an apparent size larger than the full Moon.

Due to its low surface brightness, M33 is particularly suited to binoculars, although you'll need a large telescope to see its spiral arms.

The galaxy is in the same field as alpha Trianguli. Place this star to the left of centre; M33 will be in the west-northwest: binoculars.
