Version 4 will not connect to SBIG stf 8300

SGP version 4 will not connect to my SBIGSTF 8300 no problems with version 3

At least for now, you’ll need to install the 32-bit version of SGPro 4. We’re looking into 64-bit support for SBIG currently.

That said, you would probably be OK just using the SBIG ASCOM driver with 64-bit SGPro.

I am fine with V3.1. What advantages does V4 have?
