I do have some amp glow with the ZWO071MC Pro. Still not able to avoid it in my light frames and/or fixing it totally during callibration
; a final dynamic crop turns the image aestetically better (see attached). In the previous post, I made a mistake and posted the image still not cropped. By the way, I use darks, flats and dark flats and no bias. I will check the calibration frames, thanks.

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!
