Description

L: 180x1mn
R: 51x1mn
G: 47x1mn
B: 181x1mn
Ha: 11x5mn

The weather has been great these past nights, so I went for a session dedicated to M101.
I planned everything in Nina and went to sleep, during night I went back and realised that I let the B filter instead of the L !!!
I changed for L but I have 3 hours of blue channel, this is still signal but I was a little angry after myself ;-)

NGC 5474 is fittinig in my APS-C FoV at 920mm focal, so I processed most of the frame to enjoy its presence.

Title: M101 - selection of best frames for Luminance Core and more Ha enhancement

Description: I was not satisfied with the various sharpening I made on the initial version, there, I did almost nothing but selecting the best L frames (around 120x1mn) - this type of selection is now to me and I am happy of the results, hence the upload of this version.
I also pushed the Ha boost a little further, I love the tiny red dot in the center of the galaxy :-)
