I am probably the only dinosaur still using a parallel port camera! Got a good deal one one last year and really like it. Presently use Maxim DL5 and CCDCommander as a control program. The camera is an SBIG ST-8E with an internal guider chip. If I read the manual right you have three modes for autoguiding, none of which I believe, is compatible with those three modes, at least while the main chip is active. PHD2 is a great program and does a better job of guiding than Maxim. Unfortunately, there does not seem to be a way of controlling the guider chip with PHD and the Main camera with SGP. It looks to me like everything else can function OK especially if SGP will run the camera at all. Am I missing something in the forum or manual that would let me know what would be possible with a parallel port camera? I also run an AR102 with another newer camera and would like to try out SGP so it would be nice to run the same control software on both scopes.
