Been struggling with DSS and my Pentax K5 raw for some time now but finally have it sorted i think with some help from tips on a few threads here on IIS.
Here are a few images that have each been stacked from four or five light frames only, no darks or flats as i was and still am experimenting with equipment setup to see what I want to work with, eg field size etc and i still need to get a field flattener for both scopes as well but at least the stacking side is working and the images should improve somewhat with darks and flats from here on in, oh and the flattener of course.
I wont bother with details of the images as they are nothing special other than to say they were shot with a std Pentax K5 through my SW ED80 and also my Meade 8"sct 4-5 light frames iso 800 and stacked in DSS.

I'm happy to be making progress and I hope you like them.
Thanks for looking
