Baz, DrPaul, Doug and Marc, thank you for your feedback, opinions and compliments!
Dr Paul: yes, I used the entire matrix of the M25C. I tried using the Red channel only but it came out with spots all over the image. So I reprocessed it with the entire matrix.
Hagar: I left it soft because I have only 6 x15 subs, which are not sufficient at all. I have to go 20 to 30 minutes and way more than 6 subs! If I try to do an unsharp mask then I'm going to have a lot of noise. Furthermore, the M25C is an OSC camera and it is really NOT sensitve at all as you know
