M33 - Triangulum Galaxy
The Triangulum galaxy, also known as M33, is one of the closest large
galaxies to our own, and also one of the brightest. Although it has a low
surface brightness, it can be seen with the unaided eye from a very dark
rural site. The brightest HII region has its own NGC designation, NGC 604,
and can also be easily seen in an amateur telescope at moderate power.
