Description

Image of Sunspots AR 2993-2994 and 2995 in Ha.. WO 73 mm apo and Daystar Quarck with asi 174mm.
Because of the fast changing surface I took a SER image (16 bit) to get the maximum details.
Processed with AS3 and Imppg (with a final touch with AstraImage)  Still a lot the Improve but for now I'm satisfied so far.
Sharpening and contrast is always a personal preference but I don't think it's over the top.
