Still sounds like might be polar alignment though Troy. Something to eliminate anyway.
I guide with a cheap 2nd hand F10 refractor on my F5 reflector. Phd very reliable, except when:
- star too faint
- haven't forced a recalibration after moving to another object in different part of the sky
- mount or scope bumped
K3CCDtools includes a handy freeware tool for checking polar alignment. 1Ponders has promised a tutorial for us, but I'm sure myself or others here could provide info if you're interested in that.
