Hi Paul,
Thanks for your reply. I think it is an issue; my stars are about the shape of that guiding graph!! Certainly I shouldn't be seeing that in DEC should I? If not for those excursions that don't correct I would have terrific guiding. Thanks for the suggestion that I check the through the mount cables! I had not considered that obvious possibility!
I probably should redo my t-Point model and check PA, but I doubt this is the reason for my DEC issues, though it certainly wouldn't hurt to have everything spot on. Just takes time and tme is often short when it comes to clear sky!
Peter
