It appears that I cannot use the subframe capability whenever I use the native ZWO ASI1600 driver. I have always been able to use the subframing to assist in focusing when using the ASCOM driver, but I want to be able to set Gain/Offset on a per-sequence level and now the subframe box is greyed-out.
Subframing hasn’t been implemented for the native driver yet.
Thanks. I’ll be looking for it in a future release.
