Summer photo archived and then taken with a new processing procedure using a different path (the first one didn't convince me) I hope it's enjoyable... ;-)

Well very enjoyable. Despite the lack of calibration. Congratulations Marzio

Thanks Marzio, but excuse me, I don't understand what you mean by 'lack of calibration'....

You do the calibration when you subtract the dark, flat and bias in the stack phase. I read in the caption that you only used 6 dark.

Never used neither bias nor flat, I tried several times (for all the photos I took, not only for this one) without any benefit, so.... ;-)
