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....

Just a cellphone pic but managed to pick up 3 planets - Venus, Jupiter and Mercury. You might need to zoom in on the pic to see Mercury (or at least what I assume is Mercury based on Stellarium positioning) towards the top of the tree on the left.

ALL the foreground stars you see are all within our Milky Way Galaxy
Yes - in retrospect that should have been obvious. Even the highest resolution pic of our nearest galactic neighbour, Andromeda can only resolve stars as tiny yellow dots.

Deets: nikon D810 + nikkor 800/8, 1/5s, ISO 1250, straight to jpg. Maybe you prefer the 1:1 crop:

Witch Head Nebula, acquired winter 2026, with Seestar S50. Ploiești, Romania, bortle 7.
Due to weak signal, processing was a challenge.
1 hour total integration time, stack with ASTAP, processing and editing with Seti Astro Suite and Photoshop.

My final attempt imaging Hoag's Object (PRC D-51, PGC 54559):

Maybe you can discern a faint circular glow around the center dot. Deets: Nikon D810 + Nikkor 800/4 on Losmandy G-8, 10s subs, 13 h total integration time, stacking etc. with AstroPixelProcessor.

I'm not entirely sure this is a 'fail', I knew the apparent magnitude of the ring (16) was near the detection limit I calculated a while ago, but I was hoping that with sufficient averaging, I could pull it out of the noise. Remember, the magnitude of an extended object is calculated as if all the light is detected by a point detector. I can see a faint whisper of LEDA 3843622 and 2MASS 15173403+2134060 at the bottom center and 2MASS 15173523+2139214 bottom left edge, so that's encouraging.

Wow, that is a great photo. Your telescope imaged a galaxy nearly 600 million light-years away.
