Hi,
I've been going through old data recently tying to improve on previous attempts at processing. My main aim is to bring out fainter background nebulosity.
I'm surprised how much more was in this image of NGC 6188, certainly going to reimage with longer subs.
Supplied, repro left - original right.
Telescope 8” f/4 astrograph on a HEQ Pro 5 mount, orion mini guider.
Unmodded Canon 1100D at ISO 800.
13 x 300 sec subs ISO 800.
11 dark frames, 9 flat frames and 9 bias.
Stacked in DSS and post process in Phototshop.
Cheers,
Justin.
