The seeing was pretty bad for most of the data, FWHM's of 3-4 arc sec most nights. I ran the raw data over CCDinspector...there is a definite tilt in the system which I suspect is blowing out the data a good arc second or more. I'll try and fix it tonight.
3-4 arcsec?! YUK!!! That certainly explains your scaling! I don't bother imaging Lum if seeing is beyond 2.5 and I'll throw away subs straying over 2.5 in any case. If I don't stick to this, even after decon I get a frame full of fuzz balls. Hopefully you'll get a couple of good nights soon!! I find the warmer nights have a better chance of good seeing around here (somewhat counter-intuitive but empirically true).
Looks very sharp Peter considering seeing conditions.
Around the core and dusty regions look little dark but it sure does made the detail pop out.
Stars are looking lovely too.
I would be stoked with such an image
