Hi Larry,

I think I meant that considering nothing changes (like maybe in a permanent setup). More accurately, you will usually need to do the calibration wizard once per night. However, if you change equipment or camera orientation then you will need to calibrate again. If you do a pier flip, you don't necessarily need to calibrate, but you may have to invert the PEC curve.

Ray, excuse me for butting into this conversation. But the reference you made about
the Calibration Wizard says you only need to do this once. Is this also true if I
remove the telescope/camera and later replace it on the mount (a refractor) and the
camera angle is slightly off from its previous position?
