Ok, and I am assuming that that generates the .fits file which represents the completed in camera imaging/stacking process saved as Stackxxxxxxx.fits. But when I look at the individual images saved to the device and move them to my pc, there are only Light frames in the Sub folder, no darks or bias one to use for stacking in third party software.......so far as I can find out, even the ZWO DeepStack application in their ASIStudio program needs at least dark frames to properly stack the individual images, because when I use just the Light frames there is no resultant image that can be opened in an editor to process.
Many thanks for your assistance and patience!
