Not watched it yet but looking forward to it.

Anything that you have to set up each time will still make for a
wobble between images. If there is a good solid post or object that
you could attach something like a Cullman quick release unit to that
would enable much better
repeatabilty:

The square plate detaches from the base and fixes to the camera. The
base, the bit with the lever, you fix to the solid post/object with
at least two fixings (to stop it rotating). Pop an old small
fertiliser/compost bag over it to keep the worst of the weather and
prying eyes away.

Even a few blocks of wood fixed on the solid object that hold the
base of camera in the same place would probably do but watch of
front/back tipping if using a modern camera with narrow base.
