Hi Han,
That sort of field of view isn't unheard of – a standard 1280 x 960 guiding type camera with 3.75 µm pixels on a 750mm focal length telescope would give a field-of-view of about 0.37 x 0.27°. I'd say that was likely to be a moderately common set up given the popularity of those cameras and of skywatcher refractors with a 750 mm focal length.
Unfortunately SharpCap doesn't know anything about the focal length of the telescope, although I usually have the pixel size of the camera which could be used to work out the image sensor size. If you combine that information with a reasonable range of focal lengths from say 200 mm to 2000 mm then maybe we could restrict the search range somewhat.
Cheers, Robin
