Hi Peter, Newbie on this forum but have been messing with AP for a year or two and was interestingly reading this thread as i image with an EQ3 synscan when i came upon your image - and thought how similar it is to my recent attempt but from a totally different approach. Recently i have given up on stacking images and just gone for single long exposures - this is a SINGLE 407s exposure, 130 pds scope with CC through a modded dslr with a cls ccd clip filter fitted, guided with phd, and then about 30seconds worth of tweeking of the raw image in an old adobe elements. I got a bit fed up trying to learn pixinsight(trial) and gimp as i'm not the quickest learner on a computer!
I would be very interested to hear what people think of my attempt - criticism gladly accepted
