Ah, but thats the catch Marc. MaximDL when connected to your scope via ASCOM will read the declination information and use this to compensate for guider movement. Providing you get good calibration once (nice red L shape indicating movement), then you can technically shoot anywhere in the sky and not recalibrate. I've not recalibrated for over six months and shoot objects at various declinations. Guiding is spot on. If however you have a temporary set up in which you setup and tear down each night, changes to the guider PA will alter the calibration.
