Description

M45 again. 

I love this target as it is very beautiful with colorful stars with a haze of bluish nebulosity. I can always find rooms for improvement every time I come back to this cluster. It is the logo of Subaru and also called the seven sisters clusters. On a good clear night you can visually spot 7 bright stars in a small area in the sky.
