Drift Alignment Made Easy
This method is for refractors or SCT’s using a star diagonal. Reverse altitude adjustments, if using a star in the west for second star. Reverse all adjustments for newtonian telescopes.
- Level tripod.
- Roughly polar align mount, preferably with a polar scope.
- Pick a star on meridian, just north of celestial equator.
- Orient eyepiece crosshairs with north-south and east-west axis of mount.
- Place star on horizontal crosshair. If star drifts up, adjust mount in azimuth to move star right. If star drifts down, adjust mount in azimuth to move star left.
- Place star back on crosshairs using hand controller.
- Repeat adjustments until no drift is seen for 5 minutes.
- Pick star in east, just north of celestial equator, about 20° above horizon.
- Orient eyepiece crosshairs with north-south and east-west axis of mount.
- Place star on horizontal crosshair. If star drifts up, adjust mount in altitude to move star down. If star drifts down, adjust mount in altitude to move star up.
- Place star back on crosshairs using hand controller.
- Repeat adjustments, as necessary, until no drift is seen for 5 minutes.
