Geez Dave, load up the grief why dont you ;-), Ive got a long way to go (and I havent posted a pic in mths, not good).

Yes, and there are heaps of video how-tos on the web, although I havent seen one on guiding live with a graph in realtime. It depends a lot on the rig of course, every set up is different.

Its supprising what a graph can reveil, over/under agressiveness, backlash, polar alignment, balance, stiction, PE, mirror flop, loose fittings, seeing (related to guide exposure time, very important, to avoid chasing seeing or conversley, under correcting). The guide error graph is the realtime indicator of exactly how your mount is performing, in "graphic" detail ;-).
