Looks very promising Bert...colors look fairly close to what I expect from a normal RGB image. I agree that would be a great way to go deep where lots of LP is unavoidable. The achro seems to do a rather good job at it considering how bad a 150mm f/5 would be. Still shows some minor CA around the brighter stars which I don`t know why?
With many exposures you would end up with a very nice image but I reckon your ED100 would be the instrument of choice.
Look forwards to further refinements and updates!
cheers Gary
