helped with angles

On CloudyNights, in the double stars forum, jjbroomco asked for some help with measuring the exit angle of drifting stars. I gave a few suggestions, such as repeating drifts, and verifying dead centre, if possible. He replied.

Great suggestions, thank you.  I agree, the more data points, the better.  I will try more than one drift.  I do have a 12.5 mm reticle eyepiece that I use for GoTo alignments.  I will give this a try as well.

Good stuff.
