Description

Here is a new shuffling of the cards : a smoother reprocessing of M101 with a better choice of my subs !

I feel a bit more satisfied with this work...

VERSION D : reworked on the gradient removing process...

16x 300 sec in UHC + 15x 120 broadband + 29x 122 sec broadband all @ 2000iso

VERSION E : cloudy nights and nothing else to do, so I revisited my data, used many layers to treat colors more to my taste, median noise reduction, local contrast, etc. finally, a heavy crop, and here we are, until more data acquisition !
