Align to the zenith (or any other fixed point)
Keep the telescope in perfect vertical (using bubble level) and align using the zenith coordinates.
Reopening, because I think there is potential here for creative uses that I hadn’t thought of before.
Such as aligning a radio antenna to East (as suggested by Adrian on email).

This might be a good idea if the user has already performed a leveling of the mount and knows that they have the OTA pointed directly upwards by way of a level. If the location has no view of the NCP is not possible could some other point work?/ like three or four far away points? Bridge top, antenna, things that don't move. Set up before dark, ready to go early?

I'd like to use SkEye + sensor device (wiced sense2) to turn a Yagi radio antenna by azimuth. Usual align can't be used (I can't see what antenna sees - antenna is out and high on a tower).
It would be great to have a special align procedure, asking to point antenna to N, then E, S, W, in order to acquire a good azimuth accuracy.
This procedure can also be used to fast align a lunette or binoculars in 4 points for azimuth.
