An 8" Mirror Cell for John in Tuscon, Arizona....

Here's a "simple 6-point" cell for John's 8" primary mirror.
The O.D. of the backplate is 9.5". His mirror is 1.5" thick,
so a simple all Baltic birch cell will work just great.

Easy collimation with thumb knobs. John will affix his mirror
to the cell with silicone. No mess, no fuss.
