GPS Alignment
I have the Celestron 8i with the GPS. After a GPS alignment and just before the
time verification the telescope is not pointing north or is not level. Is this normal or should the scope be positioned level and north at this point before it continues? Harold |

Is this normal or should the scope be positioned level and north at this point before it continues? This is normal. Basically, (for example), the 'level' detection, does not involve finding 'level', but the point at which a small detector 'switches'. This will differ from scope to scope. Once the detector is calibrated, the scope knows where the 'real' level is, compared to it's sensor, and will know how much adjustment to make to find the stars. The same process is involved with the compass sensor. So the accuracy with which stars will be placed will depend on how precise the measurement is of this error. The scope has options to calibrate the level, and calibrate the compass, which should be performed after getting an aligment as accurately as you can manage. It'll then know how far off the detectors are. Best Wishes |
