C

The last two revisions are made from scratch using SubframSelector to weight the exposures. Additionally LocalNormalization with the highest weighted frame as reference is used. This is the drizzle integrated version.

D

Final version with more noise reduction., TGVDenoise.

F

After looking more at Local Normalization a new processing is done. Reference image for LN is now the one with less gradient among the "beste" subexposures

G

Star reduction
