Every camera in the catalogue on this telescope, at 490 mm and f/7.0. 52 pairings have a page; 1 sensor is larger than the stated image circle and listed without one.
No corrector for this telescope is in the catalogue, so these figures are at the native focal length.

Figures from the maker’s page. Source. Provisional: the row has not yet had a second, human check.
Every camera
Sampling is the star’s FWHM in pixels at 2.5″ seeing; every band is a tradeoff, and wide fields are undersampled on purpose. Each camera name opens its page.
