After too much imaging time wasted after poor polar alignment and subsequent difficulty with phd2 calibration I've pulled the pin and ordered one; shipping now.
I'm in the southern hemisphere and have a mobile rig. Taking it to Tassie for a month in December too so I don't want to be wasting time there!
Found this excellent demonstration video by AstroNZ on Youtube for us southern hemisphere folks. Will write my findings when I give mine a run after the next New Moon (clouds depending of course, it's been a lousy winter).
