I have posted two pictures of Jupiter at Astrobin:

I believe this is near the top I can get with at 280mm scope.
Considering the focal length to be 5000mm then the Dawes resolving power shall be 120/280=0.428 arcsec
A pair of stars separated by this distance shall have a separation of 5000*.428/206265=0.01mm=10um so basically to satisfy the Shannon rule the best size for my pixels shall be 5um but better stay a little lower (double sampling is really the bare minimum) so about 4um.
The pixel size on my camera is 2.9um, so the green has a sampling period of 4.1um which is good, but the red and the blue have sampling period of 5.8um due to the RGGB bayer configuration.
I would want to ask expert users if they can see there is undersampling in my images.
Thank you.
Kind regards,
Gianluca
