Photo description / processing

Testing a modified mini Newtonian telescope for astrophotography on a homemade star tracker. So far, it can't handle exposures longer than 30 seconds, which is too short. Working on reinforcing the structure—maybe something will work out...

I tried processing it in PixInsight. My first attempt.

Nice picture. I gave it a plus, but I wish the noise had been cleaned up.

Thank you! I downloaded the trial version of PixInsight to try it out. I uploaded a new version. It turned out better)

This version is much better in terms of noise and looks more pleasing. However, it lacks that "crisp sharpness" of the first one. Consider my take on the first version. In it, I used Imagenomic's noise reduction on the highest frequencies in the shadows and midtones, and sharpened while slightly dulling the stars in PixInsight. https://disk.yandex.ru/i/0OeEb7JP__L7gA

I'll try some more processing. Clear skies aren't forecasted anyway. I'd like to increase the exposure time, but I'm not sure if my tracker can handle more with the Newtonian. Otherwise, I really enjoyed the first experience shooting without chromatic aberration.
