RE: [ATM] Berry's 10-inch telescope plans

Remember that anything that you make out of plywood (even 3/4") is going to
be MUCH lighter than the commercial scopes that use particle board.  I don't
think that weight is going to be much of an issue for a 10" scope if you use
quality plywood.

 Hello Thomas,
  When first I made my 10" thats the plan i used(If
 memory is correct)is it the one with the mirror cell
 mounted to the end of the tube?
 I thought of using 1/2" ply at the time also but
 decided in the long run to use 3/4".
 As far as weight goes the mount by itself weights in
 at 26 pounds which is not to bad i dont think and if
 you wanted to lighten it up more you could cut a
 design out on the sides and front (something I plan
 to
 do),there are always ways to make it lighter.
 I suppose the 1/2" would work,  but remember the
 steadier the mount the more enjoyment you will have
 in
 the long run, I decided on the 3/4" because I
 figured
 the 1/2" would induce vibration or even warp over
 time.
 Black forest telescopes use to have a site up with
 some beautiful mount designs with the inner parts of
 the mount basically hollow, really nice but I can no
 longer find thier site... anyone have a link to it?
 Good luck with the telescope, btw what is the F
 ratio?
