Does anyone know of a website showing example images in ranked order of the relative brightness and clarity for an M object so that I can better understand what I will see if I purchase a Dobsonian Telescope with mirrors 10" and 14"?

The Obsession Telescope web site has a rough comparison of images of M13 in various size scopes.

I would say the difference between 10 and 14 is noticeable but mostly not shocking or WOW worthy. I went from 6 to 16, and that was a WOW. As always, try to view through some other scopes if you can.
