Try as I might, I can only count 14! That is, spiral galaxies. Some of those rounder, smeary ones are probably galaxies too, but I can't distinguish blurry stars from globular galaxies. I'd need an astronomer to help me out!
Only 14? Every blurry smudge and spiral thing is a galaxy. There’s probably at least 30 or 40 easily identifiable in this picture. You can discount all the small blue dots, everything with diffraction spikes, and just about all the other smaller dots. You’re basically seeing the galaxy cluster through the nearby field of stars in our galaxy. It would be nice if they could edit them out.
