My 6" Newtonian Reflector mounted on a Charles Frank manually driven equatorial mount. My ever supportive parents bought me the scope when I was a teenager. The 'run off' observatory was designed by my dad and we spent several enjoyable days during the summer of 1980 building it. The scope lived quite happily in the observatory for around five years. The bulbous counterweight is in fact a jam jar filled with concrete and painted white!
