I just ran across info about an ASCOM driver for legacy SBIG cameras developed by a private individual referred to as “Cedric-r”. Since I have an old ST-2000XCM, I was curious to test this driver. Short story - it works. There are also reports of it working with the STF8300. This test was run in a 32bit environment. It only supports the older cameras using a USB interface.
You need the installer:
You also need to, first, download, install and run the SBIG driver checker utility to install the needed SBIG support libraries and USB driver.
The SBIG ASCOM installer also installs an ASCOM interface for the built-in SBIG guide camera. I verified that PHD2 Guiding can connect to it and download images.
Finally, the installer also installs support for the older SBIG filter wheels. I was not able to test that since the ST-2000XCM is a OSC camera and doesn’t have a FW.
