In a related issue -- I normally image with a QSI camera but I own an older SBIG ST-2000XCM. After seeing all the new software and firmware releases from SBIG, I decided to connect up my ST-2000XCM to SGP (2.5.1.14) and test the camera's operation. I updated everything to the newest SBIG drivers and installed SGP API.
SGP connected to the camera and PHD2 Guiding (2.6.1dev8) also connected to the SGP API ASCOM camera. PHD2 had no problem getting frames from SGP and I never saw any failures in PHD2. However, when trying to get bias and dark frames from the ST-2000XCM, SGP would randomly crash. Using a sequence file with an event for bias frames and an event for dark frames, sometimes all the frames (64 each) would take and download but other times the sequence would take a few frames and crash.
Most of the time I had to cycle power on the camera and restart SGP before SGP could reconnect to the camera.
I'm primarily interested to see if anyone else is using SGP with the ST-2000XCM camera successfully. This is a somewhat old camera and it is possible there are issues with the camera itself or perhaps it's just not fully compatible with the new SBIG drivers or SGP.
Having PHD2 running or not running did not seem to have any effect on whether SGP successfully took and downloaded frame or not.
I'm not planning on any serious imaging with the ST-2000XCM and the new version of CCDOps seems to work OK. But it would be nice to tell a prospective buyer that it works with SGP.
