Tom's 12.5" Strut Telescope -- A Cell . . .

A 6-point flotation mirror cell for Tom's 12.5" mirror. These
mirrors cells are designed  and optimized with Plop.

Easy to collimate with knobs, vent holes for cooling.

Here, the mirror cell is affixed to the back of the mirror with silicone.
Once the center of mirror is "center marked" the cell is lined up using
its center  hole. I use the plastic "sight" to be sure the alignment is right on.

I give the silicone 48 hours to "cure".
