The M33 Triangulum Galaxy


Just about six hours' worth of data on this galaxy used for this image! This was taken with my new~ish ZWO ASI2600MC Pro camera. Very pleased with the result. I may try for some Ha data to compliment this later...

M33, also known as the Triangulum Galaxy, is a nearby spiral galaxy located in the constellation Triangulum, about 2.73 million light-years from Earth. It is the third-largest member of the Local Group after the Milky Way and Andromeda and is characterized by its patchy spiral arms, containing numerous star-forming regions like the bright NGC 604 nebulae. M33 is a "pure disk galaxy" and lacks a central bulge and a supermassive black hole, a unique feature among large spiral galaxies.
