Using Version 3.2.5986.0
- I have a ZWO ASI 178mm camera (14 bit ADC)
- I have this setting checked: General->Saving->"Save 10/12/14 bit images in FITS files without scaling to 16 bit [...]"
The setting works as advertized when I capture frames via "Quick capture" or "Start Capture", in the sense that the max ADU value I'll get is 2^14 this way, but when I use "Capture->Capture Dark...->Dark-Library checked , the resulting dark frame that is stored in the dark frsme library directory structure
is scaled to 16 bit. This is perhaps a bu, at least it is unexpected and counter-intuitive. It requires an extra step of dividing the drak frame by 4 (in my case) before subtracting this from light frames in external software.
Is this intended or a bug?
