Hi guys.Drift is usually the result of improper polar alignment. I would look there
For polar alignment, you can do a classic drift align, and that would be
the best way to check.
Secondly, make sure that your keypad is set to Sidereal. The previous owner
might have set the tracking rate to Solar or Lunar.
Finally, please note that you will always have some RA drift, even when
perfectly polar aligned and running at the sidereal rate, because the stars do
not follow the sidereal rate everywhere in the sky. Any time that you are
more than 15 degrees from the zenith, you will get some RA drift. The further
you are from the zenith, the higher is the RA drift rate.
