Jase - Cheers for the link, very helpful..
I've been playing with luminance layering using my QHY8.. I've had mixed results... but I've always noticed that by adjusting the opacity of the lum the resulting stellar profile is much more pleasing....
The shot of 2516 could probably do with a repro keeping the stellar profiles in mind, although I think it was shot during my earlier days with the QHY8 and I had my gain/offset at something like 50/110 or the like.. so the profiles might have been clipped from the get go..
I'll have another look at the raw data and get a feel for what can be done...
Cheers guys..
Alex.
