Solutions:-

1. Go and look at something else for an hour or so until the object of interest has moved away from the zenith.

2. Prop up one side of the base board on a brick, therefore moving the "hole" away from the zenith (where the object of current interest is).

3. Perfect a way of moving the OTA in the azimuth direction with a two-handed approach. Keep one hand on the top of the tube. Reach down with the other and grasp the base at one of the corners and rotate it in azimuth that way - grab it where-ever you can get some mechanical advantage. If you have a stalk for an Argo Navis or something connected to the base (eyepiece rack?), that can be a good point to use.
