Family photography v's astrophotography??
Why is it we always seem to end up going back to the ol' days of family photography when discussing telescope/ camera set-ups for astrophotography?? APS-H, APS-C, micro four thirds 4/3" etc etc
The "total pixel count" and "frame size" of standard camera chips doesn't mean all that much to the AP......
The pixel size, QE. and chip size (in pixel/ mm) to allow analyse the plate scale and possible resolution are important. The telescope aperture and effective focal length then give us the light gathering/ resolution and plate scale of the image.
