| The most convenient place to mount
a finder (in my experience) is close to the eyepiece, assuming the
telescope has been pointed very close to the object with the use of a
telrad or something like that. I like pointing the scope with a telrad
without standing on my ladder, so the telrad must be placed low enough
, even if the object of interest is high in the sky. This means it will
have to be placed on one of the trusses. To accomplish this I made a
ballhead mount for my telrad, which can also be used with a not too
heavy finder instead of a telrad. It's really very simple.
Take a piece of 18 mm thickness scrap baltic birch plywood,
or some other piece of wood;
drill a hole through the plywood, of the same diameter as the
trusstubes;
cut the plywood into two parts, lengthwise
connect the two pieces with a small hinge;
glue a 5-6 mm nut into one of the parts, at the side opposite
to the hinge;
mount a piece of threaded rod, glued into a knob, to the
other part of the plywood, such that the threaded rod can be screwed
into the nut;
epoxy a camera-bolt into one of the wooden parts at the side
of the hinge;
glue a camera-nut into a hole, drilled in another piece of (9
mm thickness) plywood, on which the telrad will be mounted;
assemble all parts a shown in the pictures and mount the
whole assembly to one of the trusses.
