So many galaxies! Hard to imagine the scale involved. Could some of the "stars" we are seeing also be galaxies. Maybe just smaller or alternatively further away ? Can a star be distinguished from what might just be a more distant galaxy ?
I know! It's sobering to contemplate the vastness and our insignificant place in it.

I typically run the image through Astrometry.net to identify Messier/NGC/IC objects, but it doesn't get all of them (for example, UGC and PGC catalogs are not included); often distant galaxies can be distinguished from stars because (in my images) they look a little blurry. I haven't run this image yet, but I suspect there are at least 300 galaxies visible....
