Like everybody else, I had to build one of these. This one is made of
brass and walnut plywood left over after I built an 8" f/6 Dobsonian
for Robert Haag (the "Meteorite Man"). The legs of the tripod are made
of unstained maple. The tracking is very good allowing exposures of
over 10 min with a 28mm lens and four to five with a 50mm lens. See
these pictures of Hale Bopp for examples.
