i noticed on the last couple of runs that SGP puts up a dialog when quitting to the effect of “can’t end exposure - SBIG driver not open.”
my camera has been acting up a little so i ignored this the first time. i haven’t made any changes to drivers or firmware, so i think the only change is SGP. i thought maybe this had something to do with the guider API so this morning i also quit PHD2 before quitting SGP (but i had of course disconnected all equipment from SGP before that. maybe i should have quit PHD2 first).
anyway the error seems rational; the camera is disconnected from SGP when SGP complains that the driver is not open. however, there should be no image in progress at the time.
would the log shed any light on this? i can post it.
