Only from NGC604 to NGC588.

I tried to show all this beautiful Hα regions with a maximum definition on the context of this galaxy, covering a half degree region.

I prefer to keep this object as diffuse as is but searching the max resolution that I could obtain with my equipement. It was necessary to integrate close to 29 hours of frames.

It’s a very common object, I hope to show you a different perspective! 😀

“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. It is one of the most distant permanent objects that can be viewed with the naked eye.” (credits Wikipedia)
