Gx cameras allow arbitrary combination of hardware binning in both axes in the range 1 to 4 pixels. So 16 combinations from 1 × 1, 1 × 2 up to po 4 × 4 can be created.

Astroart drivers do not inform about possible binning ranges in both sensor axes, but have to enumerate individual combinations one by one. Driver author overlooked information, that Astroart at the same time limits number of binning combinations to 8. If the driver function, returning total binning combinations, returns greater number than 8, Astroart 6 does not just crop the number, but reports an error. The new driver respects this limitation and cuts the possible binnings for Astroart users to a number, which Astroart can handle.
