Hi
 Let me see, a piece of 2X4, some cardboard, a handful
of staples, a hose clamp, some black spray paint, some hot glue, a piece of
sink plumbing and some imagination. I have eyepieces so that would make a
fine telescope. A f/20 wouldn't have as much troubles with collimation so
that can be a little crude. Dwight
