Hi Paul,
Don't know if this is useful, I imagine you have already seen CCD Calc by Ron Wodaski. If you have an earlier version a newer full version can be downloaded for free below. You can use the various scope camera combinations or create your own camera/scope setup - good for your new GSO RC.
"in all version since Version 1.2, you can create your own telescope and camera entries. It also supports the latest version of
Automapper - Automapper can read the latest CCD Calc image scale from the registry."
