Hi Robert,
What I am going to do is take advantage of the never ending clouds and rain down here in Brasil to rebuild all my calibration frames. I will see how it goes.

Hi Fernando, I'm surprised by the amp glow. I have the exact same camera and run at -5deg, often 3-5min subs, as you are and have really pushed it in post-processing and have never yet seen any evidence of amp glow after I've calibrated. Haven't really looked for it is the lights but have never noticed any there either. Wonder if something unique to your setup that's in play if not something wrong with calibration frames. Let us know if you find the culprit![/QUOTE]
