Gorgeous shot. How do you manually dither?

Thank you. Very simple but very demanding physically, Stop imaging, use hand control to move the mount around 5 to 10 pixels randomly every 10 to 20 minutes depending on the setup… no dodo during the night! Nothing will come easy.

Lovely image. Here is mine from 10 days ago or so. 2.5 hours integration time. 2 min subs. Nikkor 180mm f2.8 stopped down with step down rings. ASI 533 mc colour camera on a iOptron skyguider pro. Class 1 dark skies but pretty awful seeing due to intense humidity in the air. APP and PS

Very sharp!

I see there is a lot of colour you can pull out of even the jpg.
