Thank you. But does it include darks in the FITS files it saves? I would like to add darks and flats when I do my post processing and IIRC there is a blank in the filter slider that creates darks. I can create flats by putting a white tee shirt over the unit and aiming at a light but I would like to utilize the built in dark "filter" instead of putting a cap over the lens. So is it possible to manually create darks as part of the FITS files it saves?
