I then repeated the experiment using the C8300 as the camera, here's the log ...

... which had this as the initial condition ...
... and resulted in this as a captured image ... not a nice dark, a uniform white (sigh) ...
To verify that my camera wasn't wonky, I then loaded up MaximDL 6.13 with first the native C8300 driver and did the same exposure ... here's what I got, a nice dark ...
... and realizing that SGP uses the ASCOM driver for the camera and not the "native" driver that MaximDL uses, I then reloaded the Maxim camera with the C8300 as driven by the ASCOM driver ... and another nice dark ...
It's pretty baffling, I didn't see anything strange in the logs between the SSAG and the 8300 and it seems to be performing OK under the native driver as well as under ASCOM for MaximDL. The SSAG experiment worked properly, which means that SGP is doing what it needs to do for the focus/ capture/ display path, just not for the C8300. The crosshairs are being displayed on both images as well ...
(sigh) Like I mentioned, I'm OK for using SGP with my D90 and G3 (which works well) and when I need to use the C8300 with the miracles of COM automation and AutoIT and a lot of elbow grease I can craft together something where the SGP events instead of taking lights just call scripts which control MaximDL captures, I'd just really prefer not to ...
Thx again!
