This is a 1976 photo of my friend, Master Machinist Bill Loumaster, and the telescope he designed and built. Bill discovered he got more enjoyment making it than using it and so he sold it to me around 1975 or 1976. The optics, a 12.5" f15 Dall-Kirkham, were purchased from Coulter around 1974. Except for the optics, the design is his and he made everything himself, including the drive gears. The telescope tube was made from rolling fiberglass cloth and resin to a wall thickness of 3/16th of an inch. Bill won a Unique Design award at the 1983 Riverside Telescope Makerís Conference.
The back plate is removed to show the mirror mount and focus drive mechanism. The mirror mount was made from 1/2" square 1/16th" wall thickness steel tubing. The small DC tape recorder motor turns a shaft that is under spring pressure against a flat surface on the focus tube. Turning the shaft moves the tube. Bill designed this method for focusing in 1975 or 1976.
