Added more data to this - total 3.91 hours of 30 sec subs - captured on the S50Pro, half of them on a very moony night. Not entirely happy with how the stars look, but the Pelican Nebula (IC5070) is pretty good #Astrophotography #StackingWizard #AstroWizard with #RCAstro tools, final in #Photoshop

Or maybe the answer is none of the above. Keep the greatly reduced stars but don't darken the background quite so much so more extended faint details are visible.

I got some more data on the Helix Nebula too, now totalling just over 11 hours. I think this is about as good as it's going to get with the Thirty Millimetre Telescope.

Another glow up, though this time I also had some additional data to add to the stack as well as updated processing methods.
It's the Cat's Paw and Lobster Nebulae.

I continue to practice my processing skills: here’s another go at the Western Veil nebula, 2400 light years away.
It’s not been possible for me to capture new data lately, but I do have fun learning more about Pixinsight and the RCAstro tools.
