Having got a solar filter for my ETX 105 just in time for the Transit of
Venus, I needed a solar finder (sun sight). I made one out of a 35 mm
film canister bydrilling as small a holein the middle of the base of it,
so the film canister acts as a tiny pin-hole camera.The canistercap is
clear buthas a ring and a dot cast in the middle, which makes for easy
solar alignment.The canister fits the finderscope holder perfectly,
andthe screws allow easyzeroing. With the normal right-angle
finderremoved,it doesn't poke you in the bridge of yournose whilst you
look through the eyepiece.
