I'm using an ASI-174 for guiding (with an OAG) and an ASI-1600 for imaging. When I try to connect SGP to the imaging camera it *always* connects to the guide camera. They show up as "ASI Camera (1)" and "ASI Camera (2)", but regardless of which I select, I always get the ASI-174.
It would be nice if the ASCOM driver made them show up with their model numbers so the correct camera can be selected.
