  • $\begingroup$ I agree it's a part of the answer. However, let say you configured your telescope properly (did a northern pole alignment and pointed to a bright star, and set R.A. correctly). This means that you should be able to point it at any location and get specific (unique) coordinates. However, I can easily go through a northern pole and change DEC in one direction vs another and get the same coordinates for two points. It looks like I am missing some rule of telescope usage (something like "If you go through northern pole, you need to configure R.A. spinner again) $\endgroup$ Commented Sep 17, 2021 at 13:58

    $\begingroup$ You are correct. "If you go through the pole, you need to configure R.A. circle again." Likewise, you need to reset the R.A. circle after a sufficient length of time has elapsed. If you do not move the scope at all (and assuming any motor it has is turned off), the circle says it is pointed at the same R.A. all night. But as the sky rotates, the R.A. is changing continuously. $\endgroup$ Commented Sep 17, 2021 at 15:40
