M33 - The Triangulum Galaxy

Messier 33 (M33), also known as the Triangulum Galaxy, is a famous spiral galaxy located in the small northern constellation Triangulum.

The Triangulum Galaxy is the third largest galaxy in the Local Group, after the Andromeda Galaxy and the Milky Way.

It is also the second nearest spiral galaxy to the Milky Way.

 

This galaxy lies at a distance between 2.38 and 3.07 million light years from Earth.

Charles Messier found the object and catalogued it on August 25, 1764.

 

A lot of "First Time" for this pictures. Multiple Nights Stacking, Ha and RGB Combination, First Real Session with the New Refractor, First Time Drizzle.

 

This pictures was supposed to be about 4 days, but the first was a Full Moon day, so I had to drop all my subs.

After that, I had 3 mostly clear nights to shoot with the LPRO & the L-Extreme. I had to drop a lot of subs because of clouds.

The Post processing took me a lot of times (I "gave up" a bit and switch to the data of the Pacman Nebula :p) as I had a lot of things to learn. But the final result seems me pretty cool as I wanted to keep the color "natural" as much as possible.

 

Really happy with the result.

 

Clear Skies to you all !
