Left is a 6-point flotation cell.
Right, a Meade Lightbridge 18-point mirror cell.

The two 16" telescopes are coming together. Here you see the mirror cells mounted on the mirror boards. See captions for details.

The 6-point cell is more than adequate to support the 16" mirror and has been optimized with Plop.

A rear hole in the mirror board now only looks pleasing
but allows very adequate ventilation.
