Two nights ago after restoring my Starsense, SkySafari app, etc., everything worked perfectly, i.e., three-star, manual alignment and calibration. Last night I started with a successful, three-star alignment and received the message, "If this is the first tiem....you will need to calibrate." The scope was off target and, in fact, needed a re-calibration, which I did and everything worked fine from that point.
My question is why did I need to do a second re-calibration? Was I supposed to save the calibration setting in SkySafari upon exiting the first night? If not, why wasn't the calibration saved?
