Then you are looking for something more than me. I always remember that I first plugged my camera into the scope cos I couldn;t see anything in an eyepiece. A camera was the only way to see the objects, so I'm not after an apod, just a better view. I've used almost all the software available to stack/combine except ccdstack and they are all black box, as you call it. I don't see your images being any better than someone using maxim or dss or anything else, so your controlling what is happening makes it better thoery is crap. Sounds like reteric from an air buss driver to me.
