An Owl and a Surfboard

M 97 and M 108, RGB

April 18th, 2017

Not super happy with this, but I guess this is what I get for imaging rgb in a red zone :P.

This interesting feild of view occurs in Ursa Major (commonly the big dipper), just east of the star Merak (the bottom corner of the dipper). While they appear similar sizes, really these objects are drastically different. The Owl nebula (M 97, bottom right corner) is a planetary nebula or the shell of a dying star. It is estimated to be around .9 light years in diameter, and about 2,000 light years away. M 108, in the top left corner, is an edge on spiral galaxy. At around 45 million light years away, it is far in the background. It is a member of the outer edges of Virgo Super cluster.
