Just did a crash course on Pixinsight and managed to finally get an image.
Much better SNR using that compared to DSS. I did a little editing to boost the colours and contrast but tried to keep it more natural compared to the above pic which was done in DSS.

Vlad, there are a couple of other programs I'd like for you to try and let me know which one you like more (they are all free), Besides DSS, check out Sequator and SiRiL.
I like Sequator for high SNR also, but DSS is unbeatable for removing hot pixels when you dont take dark frames (which I dont.) SiRiL is supposed to be the best (for freeware anyway) but it has so many options I haven't started tackling it yet.
Vlad are you using TEC (thermo electric cooling)?
