M33 Triangulum Galaxy

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy

 

This was a challenge to image as I struggled with constant fog and seeing problems and a 70% or more moon on every night of imaging. I never captured Ha in last years version so I wanted to highlight the numerous Ha regions within the galaxy.

Very difficult to process out the effects of the ³moon and keep the image clean, but I'm happy with the result. I cant be too picky at this time of the year when clear skies are a rarity!
