Thanks for the kind words! Yes...it's true that with higher end gear comes a higher level of expectation from everyone (myself included!) I'm cool with that, and determined to get better and processing. But I'm now a workman who can't blame his tools any more! Haha
I'm now sure that the issue was exactly what you said--very high K values in the brighter stars on the lum channel. I'll learn from that. Unfortunately starxterminator plucked out the H alpha/red globules from the continuum subtraction. Way too early in the process for me to care about it any more!
Have a happy Christmas
