Thanks all for the time messing around with the data. Guess if I really want to improve it's time to move up to a OSC cooled camera ? Or maybe a modified D5300.
A modded camera will make a big difference with H-Alpha emission lines at ~656nm but in this specific instance the Iris is a reflection nebula and has low emission in those spectral lines so it wouldnt actually help that much.
Definitely worth getting it modded though as the majority of deep sky objects have strong H-Alpha emission.You will see a big difference.
To improve your data you need skies with a super low background sky brightness level (MPSAS > 22.00) low humidity and excellent transparency.
Hardware and software will only get you so far. Excellent data is fundamentally dictated by the conditions you capture under.
Thats not to say you cant achieve great results under average skies but photometric quality skies yield mint data and make processing a simple case of putting the cherry on top. There are always challenges even with top data but life is made a lot easier when you have mega SNR.
