M106 with Michael Stecker's C-11 black tube SCT at f/7
Messier 106 (also known as M106 or NGC 4258) is an intermediate spiral galaxy at a distance of about 23 million light-years from Earth in the constellation Canes Venatici. This cropped image is a joint project of James Foster and me using my Celestron 11-inch black tube Schmidt Cassegrain telescope at f/7 (focal length= 1955 mm).
