At the moment when saving DSLR files as FITS they are scaled from 14 bit to 16 bit (at least for the Canon 60D which is a 14 bit camera). Would it be possible to have an option to save the FITS data as unscaled?
At the moment SGPro is not the most efficient way to generate calibration frames , nor is it necessarily the only capture tool that has been used on a particular target. I have historical data from other capture tools that has not been rescaled, and I can not integrate the two together.
I understand that it would not be possible to just change the behaviour as that would impact users who have set up their calibration frames / existing light frames with SGPro, but could we please have a check box in the camera configuration dialogs to write the data out to the FITS file unscaled.
 For darks it is easier to use an intervalometer and just leave the camera out without needing to setup a PC, for Bias frames I can just put the camera into high speed shutter and hold the shutter button down and for flats it is far easier to use AV mode and let the camera sort out the exposure time than it is to use the Flats Wizard
