Drift alignment is important in Astrophotography. To avoid 'Tails' on the stars in your pictures, you need to be aligned. To do that, you must first get drift aligned (after aligning your scope). You first need a reticle eyepiece, and a star directly overhead on the zenith. Center the star in the eyepiece.

Wait 5 minutes and check the star. If the star has moved up, your wedge/tripod is facing too far west... move it east and try again. Repeat this procedure until the star doesn't move up or down and is stationary for 5 minutes.

If the star has moved down, your wedge/tripod is facing too far east... move it west and try again. Keep repeating this until the star doesn't move up or down.


After you have gotten the star centered in the eyepiece, find a star on the western horizon and center it in the reticles.

Next, wait 5 minutes again and check the star. If it has moved up, adjust the wedge to move the star up in the field of view. If it moves down, adjust the wedge to move the star down in the field of view. Repeat until the star doesn't move up or down after 5 minutes.


You are now ready for astrophotography! Drift alignment is complete!
