I'm going to have to build a backyard winter
observatory. Too much of the year is too cold for sextant
work.
My thought is to put a plexiglass dome in
the roof of a small, lightweight, insulated structure that I could heat with a
110 volt heater in a few minutes. Has anyone done that? Where would
I get the dome?
If it was sufficiently lightweight, it could
be transported to beach locations for winter sights using a natural
horizon:

Even cutting out the wind would be a blessing.
Ideally it should accomodate two people for
teaching, but that would greatly diminish it's portability.
