Here is a close up of Messier 106, located in the Canes Venatici constellation. This amazing galaxy was discovered in 1781 and is one of the largest and brightest galaxies located nearby, having a size roughly equivalent to the Andromeda Galaxy. It harbors a very active supermassive black hole in its center. The small galaxy directly below is NGC 4248.

This was imaged in LRGB with shorter RGB exposures used for the stars. Additional Hα data was also taken to accentuate some of the active star forming regions.

Love the amount of detail you have captured here. Really good work and maybe the best M106 so far here.

You might have made a typo though because it's like maybe 10 times smaller then Andromeda.
