Thanks for the feedback !
I checked the properties with the view explorer and I can find the CFA path information after Debayer process but not after using the script. I should maybe try to use the "move" output option instead of "copy".
Using the script with the raw CFA files sounds a bit weird to me but I should give it a try.
Yes ! good idea
I'm testing bayer drizzle too but don't want to give up Subframe selector process.
On the other hand, I don't have good results for the moment. Too much green halos around my stars with this method.
Maybe should I try again
