I decided to take a constellation with only stars.

Stock 12’s open constellation Kassiopeija was a little boy in the early days of my hobby in my favorite visual observations so I decided to immortalize it with memories. Not very many pictures have been taken of this, or at least I didn’t find very many of them. The crowd is about 1,200 light-years away in the constellation of Kassiopeija.

Three hours exposure LRGB image.
