Traditional Declination Drift Method

 

View Facing East

Eyepiece View Facing East

Choose a star about 20-30 degrees up from the eastern horizon and fairly close to the celestial equator.  Center it in the eyepiece.  Monitor the star's movement as it drifts off the center of the crosshair.  Manually adjust the mounts altitude accordingly.

Each time you make a manual adjustment to the mount, re-center the star using your mount's hand control.  Repeat this procedure until there is no drift north or south. When finished...

Then slew to the South.

 

View Facing South

Eyepiece View Facing South

Choose a star fairly near the celestial equator, about an hour before the meridian.  Center it in the eyepiece.  Monitor the star's movement as it drifts off the center of the crosshair.  Manually adjust the front of the mount (the side that faces Polaris) to the east or west depending on which way the star drifts.

Each time you make a manual adjustment to the mount, re-center the star using your mount's hand control.   When finished...

Then slew to the East and repeat this procedure until
you have no drift in the eyepiece north or south in either axis.
