Cats Paw, Helix, Ring and Dumbbell

Had a busy night with my focally reduced ed100 and imaged the following objects with a modded 40D. All are calibrated and stacked in Nebulosity and processed in StarTools.

Cats Paw Nebula (again, but with better alignment) 21x 5 minute subs. I think the sense of depth is better with the 8" Newt but got some finer detail I think.

Helix Nebula 10x 3 minute subs. Seemed to be lots of gradients shooting near the horizon, plus street lights and a tree, so the image is heavily cropped and heavily noise reduced.

Ring Nebula 10x 3 minute subs. There was also a lot of noise shooting over the city lights in this one.

Dumbbell Nebula 3x 3 minute subs. My battery ran out of puff so only 3 shots also over city glow but it worked surprisingly well, which I guess isn't too surprising for its relative brightness.

StarTools I'm slowly getting more fluent with (tweaking here and there) although if I switch between before and after images too rapidly I can inadvertently crash the program which is very frustrating at times!. As usual any advice more than welcome. I've learnt heaps already from comments made here
