Description

This is 32.3 hours of LRGB data from this telescope: https://help.telescope.live/hc/en-us/articles/360002661697-CHI-3-100-cm-F6-8-Reflector

(CHI-3) From telescope live.

IMHO a monster diameter scope, but problematic for astrophotography due to its alt az mount and 2 piece sensor.  

The diffraction spikes rotate, relative to the camera, due to the alt az mount, so bright stars come out bigger than they would otherwise, and the gap between the two sensor halves goes right through the center of the frame, and you have to replace it with something... 

Maybe it would be less problematic if you  converted all the subs to a format Photoshop handles, and did a content aware fill on each sub, before integration?

I wonder how NASA, etc. deals with this multiple sensor issue?
