Hi,
I noticed that I am usually left with a tiny bit of "amp glow" (?) in the top right corner/side of my calibrated images and was wondering what the reason for that might be.
All images (dark, bias, light, flat) were taken with the same laptop, same chip temperature, same cables etc. Darks have the exact same exposure time as the light frames. Only difference was that for the dark/bias frames, the camera was indoors, so ambient temperature was different.
Camera:
QHY163m
1x1 binning
-15° Sensor temp
For creating the dark/bias frames, I followed Warren Kellers instructions in his book. Calibration of lights/flats was performed with PI batch processing.
20 images were stacked for the master dark
100 images were stacked for the master bias, then turned into a superbias using 6 layers.
No dark optimization was performed.
Any ideas?
