John. On your graph, it looks like DEC is only correcting one way, the blue line below zero doesnt show any coresponding brown line corrections above zero. As soon as the blue line goes above zero, corrections occur to bring it back to zero, but overshoots to -2 odd, then the blue line drifts back to zero before corrections occur again. I would have expected + corrections also as soon as the blue line dipped below zero.
And, yes your right, DEC correcting is done during tracking based on the alignment map (well at least the G11 does, I guess most if not all mounts do that too). What I ment was, if the mount is "perfectly" aligned, then no dec corrections will occur during tracking, so when guiding, only guiding corrections will occur.
