Thanks Aaron
Yep, took 15 dark frames, this helped take out a lot of the noise and I agree that the red speckling is also noise and probably a bit to much Iso.
Thats a great shot, I like the extra detail you have been able to pull out of the arms, this is what Im aiming to achieve but I need to get my exposure length up. Guide cam is coming so look out for some multi minute subs coming.
I think my processing still needs some work though, Im still learning.
