Re: Levelling 119FSA for AP1100 RA base

Being reasonably-level when setting up a tripod or portable pier is good for safety reasons, of course.

German equatorial mounts do not need to be level. They just need to be polar aligned, which does not require leveling.

I am trying to mount my AP1100 GTO AE to a permanent non-AP pier for the first time.

The bubble level is a bit off-center (see attached image).

Is this a concern? Should I put shims under the 119FSA to try to center the bubble? My application is astrophotography.
