Messier 22
(also known as M22 or NGC 6656)

© 2017 Klaus Brasch






Here is one of M-22 that I took last summer with the C-14 HD at f/7 on a night of fairly good seeing. This is a stack of 3 x 3 minute exposures at ISO 1600 with the Canon 6D and IDAS LPS -V4 filter. In my opinion M-22 is a more impressive cluster than M-13, but we don't usually appreciate that because of its relatively low latitude and smack in the Milky Way. It is truly an awesome sight in the southern hemisphere where it appears directly overhead, but there of course it has even greater competition from Omega Centauri and 47 Tucanae.
