Lots and lots of extragalactic stars.
8 inch newt, 300 second subs with IRUV-cut filter.
#M31, 9 hours from B4

Your nebulosity detail in M110 is really impressive, most super good images of M31 I've seen don't capture M110's subtle dust patches very good.
Are those numerous little blue pinpoints individual stars in Andromeda? Or is each pinpoint simply a concentrated area of lots of stars, i.e. star clusters and star birthing grounds, and due to their close proximity to one another, they appear as individual stars (the resolution in pixels per arcsecond not being high enough)?

They are blue giants and indeed individual stars. Also other big stars are visible, like for instance this one that is the star Hubble (the astronomer) used to calculate the distance to Andromeda galaxy.

Oh wow, that's actually really cool. Does that star, the one Hubble used, have a name? Like did he name it anything particular or have any other astronomers named it?
I guess that makes sense actually, that blue giants in a galaxy as close as andromeda would be visible, being some of the largest and brightest occurring stars. I've just always thought only Hubble or JWST would be strong enough to resolve something that small.

I know, really cool. Astrobiscuit also caught individual stars in M33, 2,5-2,7 million light years away. It is definitely possible vid an 8 inch scope.
But as you can see, Hubble (telescope) image has all the stars, not just the bright ones. It gives perspective.

It really does bring into perspective just how many stars are in Andromeda, the Hubble Telescope image. In that tiny little squared off section of the galaxy, there's easily dozens of thousands visible.

True.
