Looking at some frames I took of the double cluster on my  first light with this camera ( excluding just some kit lens messing around, I realized a TON of hot pixels when I was imaging at F2 with the Rokion 135. I am using a Nikon D5100. Is this really normal when using a DSLR? Is it my sensor? Is it too far gone? Should I scrap and get a new camera?
Appreciate answers in advance
Much Appreciated,
LCW Astro

I use CosmeticCorrection to take out most hot pixels (and stacking data rejection to handle more).  CC rejects thousands of pixels.  My images are just fine.

 

Don't worry about this in theory, or pixel peep subs.  See what your final images look like.

Are you taking darks as well and subtracting them?

If stacking in DeepSkyStacker, it has some hot pixel rejection built into it.  What are you using to stack your images?
