Hi,
thanks.. Thought I'd keep the same exposure length to go deeper in S and O. I have a KAF8300 ccd (WHY9S) and unfortunately in this case binning 2x2 isn't 4x sensitivity - it's about 2.6 times.
Will give it a try and see what happens...
cheers
Gary

I assume you are using your Ha as the Lum layer? that way you will get the extra detail but if not (i.e. no lum layer) you will be limited by your poorest resolution.
