I thought it might be. I'm still thinking of slicing of 20-30mm and using an old 1" extender to go back out if I have to. That way I can fine adjust the guide cam focus with out having to worry about getting the camera spacing dead perfect. Thanks for the 55mm info.
Cheers

If you're using it with a CCD ideally the camera should be spaced to give 55mm backfocus...
