Description

15 Panel LRGB Mosaic of the cloud complex. This target has been on my list for like 7 years.. But never had the chance to shoot it (The plan was shoot it when I go to a dark sky place with a widefield rig but that never happened).

This is the first time I have had widefield rig setup remotely and the FOV is too small to cover this target. I figured I shoudl at least give it a go.. and it is a 15 panel mosaic option.. and I have never been happy processing LRGB mosaics.. the gradients etc were killer.

This time, I tried to collect more panels  (with less subs per panel) per night than more subs per panel each night. The idea is to get data with similar gradients So each panel is only 3x5 mins per channel!  This worked for the L channel but RGB collection was  was super challenging with moon, clouds (This target doesn't get high for my location and there are always cloud bank). The processing has been the most time consuming one till date for me. I threw in all mosaic tools of PI (GMM, PMM etc)  on this one trying to remove/hide gradients etc.. 

Overall, I am happy to have checked this one off for now! 

Each panel has 
L / R/ G/ B - 3 (some are 4) x 5 minute subs.
