Thanks, Jonny. To me, it would be boring if every image required the same treatment. I'll even venture to say that I don't think I could replicate a finished image if I tried to re-process it exactly.
As I and many know, “it’s the little things.” The simplest effort can bring the most effective wow factor. You did it again. Thanks Chad. Oh, and that final image, holy crap! 100 thumbs up! -jason
Excellent step by step tutorial! I am trying to learn PixInsight and with your help, I climbed one more step towards the beautiful image. Thank you very much 😊
Thanks James - yeah, I think NR is one of the most complex parts of processing. I struggle with it as well. One thing I've found is that linear TGV denoise works pretty consistently on most images.
Very good channel you’ve created! I have an edge hd8 (with 1600mm and filters) and I haven’t used the scope yet, and I’ve been scared that it would be much harder to get nice photos due to the high f/7 or even f/10, but you’re getting really nice photos (of course it’s also due to your skills in editing) so I’m stoked! I have just a question about what OAG you’re using? Is it the celestron with the bigger prism or do you think it’s still possible to get nice guiding with a zwo OAG and the 120 mini? I’m on the fence of just maybe using my guide scope instead, but heard that it could create problems due to the flexion of the mirror when it focuses?
Thanks Filip! So, I recommend the Celestron OAG with the ASI174mm mini for guiding with Edge 8. The regular ZWO OAG prism is too small, and will make it difficult to focus or even find a guide star. If you go with the OAG instead of a guide scope, you'll likely get much better guiding and eliminate flexure - I generally get between 0.15 - 0.4" RMS on most nights at f/7 using my EQ6-R and the ASIair Plus. I wrote a blog post on my site about getting back spacing correct with the Celestron OAG, including diagrams and examples. Check it out if you go that route - could save you a lot of time fiddling.
You hit the nail on the head when you stated every image is different. So many factors play into it. Great tutorial!

@@ancientphotonsastrophotogr6999 I hear that. A lot of times I get asked what my process is. My answer is, "whatever the image needs".

Haha, thanks Jason. It's true, "the little things" in this hobby make all the difference. Now, if I could just keep learning little things!
I’m with ya. I preen my list of little things learned it seems weekly now. Thanks again man, you really make a difference for all of us students.

Great to see you again. Leaving one for the algorithm
Thanks Steven 🙏
Nice video Chad. I struggle with noise reduction but I have not tried TGV with a low contrast mask before. Will give that a try. :)

Thank you so much! Great tutorial
You're welcome!
Great tutorial chad! Love your processing style, keep it up!

Rista?
If I recall, his blog is where I initially learned this method a couple of years ago when I was getting my feet wet!
Consider the number of iterations - in some instances, reducing the interactions will improve the results...
