I see that the smart histogram requires Raw. My ASI294MC Pro allows RGB24 and Raw16.
If I set the smart histogram in Raw 16 and then switch camera settings to RGB24, is that a good method?
If not, how to use Smart Histogram with color? (Sorry if I missed this in instructions.)

Re: Smart Histogram in RGB24
Hi Don,
the smart histogram settings that you work out in RAW16 won't be at all correct for RGB24 - the main reason for this is that because each colour channel can only have an 8 bit value in RGB24, the effective read noise is much higher, meaning that *much* longer exposures would be required - for deep sky, RGB24 or (for the same reason) RAW8 is a bad choice.
If you are looking at high speed imaging, then I would also recommend avoiding RGB24 and using RAW8 instead - you get smaller data files and the data files are saved without any processing having happened to the data. The only real reason to use RGB24 is for terrestrial imaging when you want easy access to the colour balance controls that show in RGB24 mode.
cheers,
Robin
