Morning Derek There is no problem in converting just about any of the major formats into FITS format but in the case of the video images I have, including some from you, the largest image pixel value is 255 even if I save the video image as a 16 or 32 bit image FITS image. The reduction program refuses to display the image and apparently expects an image with a largest pixel value of 65535. So this is the first complication.... I will investigate further but unless the video image can be saved with 65535 "grey" levels instead of the normal "255" there is a problem. Maybe somewhere in the program configuration file one may be able to change this but first examination does not show any obvious place to change. I will dig up Davids article and see if that sheds more light on the subject.
