Make the appropriate adjustments to the polar axis to eliminate any drift. One you have managed

to eliminate all drift, move to the star near the east horizon. The star should be 20° above the

horizon and ± 5° of the celestial equator.

• If the star drifts south, the polar axis is too low

• If the star drifts north, the polar axis is too high.

Once again, make the appropriate adjustments to the polar axis to eliminate any drift.

Unfortunately, the latter adjustments interact with adjustments ever so slightly. Therefore, repeat

the process again to improve the accuracy checking both axes for minimal drift. Once the drift has

been eliminated, the telescope is very accurately aligned. You will

able to do prime focus

deep-sky astra-photography for long periods.

NOTE:

If the eastern horizon is blocked, you may choose a star near the western horizon

however, you will have to reverse the polar high/low error directions. If using this method in the

Southern Hemisphere, the procedure is the same as described above. However, the direction of

drift is reversed.
