I’m not too familiar of how to use Photoshop to subtract the dark frames. I didn’t know Photoshop could. Subtracting from dark frames should remove the hot pixels, unless you’re stacking everything together (your 20 subs and 2 darks) on Photoshop in which case you could merely just be adding the hot pixels.
My mistake, I should have said I'm stacking in DeepSkyStacker then doing some processing in Photoshop afterwards. Some of them can be seen in the darks but they're not as prominent... I think I need to go back and check out how exactly to stack properly to remove hots. If they're in the darks then they should be removed in the stacking process, right?

Also that RGB tinge that can be seen all around in the background where it should be essentially black - what is causing that?
