Super capture on those two Peter . Very good detail , pinpoint stars , colors right on . Another name for that M17 is the Swan neb .

Thanks Celestron. Had to crank up the ISO for the nebula. Maybe I'll start doing darks to minimise noise

If you haven't been adding darks then you definitely need to start . You should have one dark for every 5 or more shots . And remember the darks from one nights shooting are night good for every time you need a dark . Those darks need to be during the same shooting as the image your adding them to . But yes they definitely will help out on the noise for sure .

In process of building a camera cooler. That will help with ISO noise. Should get temps down to negative numbers.

Yes it will help but darks help cover bad pixels that are in each shot . That's those little red & blue specs you see all over an image at times .

I have noticed there are many hot pixels floating around
