In this photo there are actually (at least) 15 galaxies in the constellation Lynx. The NGC ones are 2825 to 2832 inclusive, and 2839. There are also four non-NGC galaxies with more obscure labels. I like to think of this photo as my own little version of the famous Hubble Deep Field photo, which shows around 3000 galaxies in a small region of Ursa Major.
