A 13.1" F4.5 for William in Novi Michigan.

Just completed is a 13.1" F4.5 with a Coulter primary and secondary mirror. The optics have new coatings and perform nicely under the stars. Note the Sky Commander and dew shield. The focuser is a nice 1-speed 2" crayford. A red dot finder is mounted on the top strut for aligning the Sky Commander.
This is the rear view of William's telescope. The mirror
cell is a hybrid of Baltic birch with an all aluminium
6-point flotation support system.
