I'm using TSX Pro 10.3.0 with my MX+
My SBIG ST2K connects to the Camera Add-on , but the ST-i fails to connect. I get this error
SBIG driver: Bad parameter. Error = 30006.
I feel the shutter click at first, then I get the error message.
I have ASCOM and ran diagnostics. That's OK
The ST-i works fine with CCDOpps (SBIG's softaware) and with MaxIm DL 6
