Re: pointing Polaris

Polaris does not sit directly on the north celestial pole. It's J2000 declination is 89 16' 05". If it were exactly on the NCP, it would be at 90.0 degrees. Even if it was exactly on the NCP right now, it wouldn't be there for long due to precession.

So, yes, Polaris and other circumpolar objects can cause the mount to go upside down and even do a west -> east meridian flip if the object is "under" the NCP.

I thought Polaris did not move at all, and its angle corresponds to your latitude? It stays at the same place day or night. Everything rotates around it.
