I was wondering if I could use a linear array CCD sensor with a 'stationary' DOB, align the linear array with the meridian and get the earth to do the scanning in the other axis !
Sony make a 5000 pixel sensor, 7 micro meter pitch which gives a 35 mm array In 4 minutes I could sweep in a 1 deg FOV in one contiguous image with impressive spatial and intensity resolution. Of course if I'm scanning away from the equator I will have to "scan correct" the image, but this is trivial once in the PC.
With a 10" f5.6 primary focus imaging the pixel resolution would exceed the scope res so one setup meets all requirements.
I accept the limited integration time limits the sensitivity but for planets and the Moon...
What am I missing?
