PS. Your greatest enemy is the weather. There are times during the year
that we must shoot every four to five days and there are other times
that we must shoot every two to three weeks. Always be on the lookout
for the weather predictions on a daily basis and, if necessary, shoot a
day early rather than risking that your proposed date will be clear.

For a mount, I'll probably use a piece of treated lumber set in
concrete. It will be on my own land, so there's no issue of other people
messing it up. That will be more than sturdy enough to stay in place for
a few years. On top I was thinking of a sort of tipped back box that the
camera would just drop snuggly into.

I don't anticipate weather being a big problem. This would be a morning
analemma, and it's usually clear then. More than two or three days of
clouds is almost unheard of. One advantage of shooting digitally is that
I can shoot on _every_ clear day, and just composite for the intervals
that work best. I can even do several versions, with denser or thinner
analemmas.
