Amp Glow Woes

[Anthonyexmouth]

As I get more adventurous with processing I've started to notice the amp glow more in my images, well one to be precise, M31, but cant replicate it in older images. 

Is this just me and some bad habit i've learnt or is it the calibration frames im using? Or can amp glow increase with a faulty/failing camera?

I'll include a light frame and my master dark for anyone feeling helpful

 

light - L_2019-09-19_23-03-34_Bin1x1_240s__-10C.fit

Master Dark - MasterDark_ISO0_240s.tif

Did you change anything between master dark and lights like exposure time, temperature, gain, offset?

Another thing that can cause issues with amp glow would be dark optimization - you need to avoid it in stacking / calibration, so check if you have it turned on in software that you are using.

Didn't change anything. Only thing different were the lights. I made sure optimisation was unchecked
