13.1" F4.5 for Russ in San Diego, California.

I've just completed a 13.1" F4.5 (based on a Coulter mirror) for Russ C. in Sacramento. Note the Easy Transport Telescope option, curved-vane spider and 2-speed, 2" focuser. A Sky Commander system is also included.

The primary mirror and secondary.has a 96% enhanced coating.

The Baltic birch mirror cell is actually a hybrid
of wood and 1/4" plate aluminium. It is a
9-point flotation cell optimized with plop.
