Jacob with Lurie-Houghton Telescope
Primary Cell Mounting Ring

PHOTO: Jacob with Primary Cell 
Mounting Ring
Here's my son Jacob with the mounting ring that will hold the primary mirror cell or mount. The three holes around the edge of the ring are threaded and are part of the primary collimation adjuster. The mounting ring will be bolted to the inside of the telescope tube near its back end. The plate or yoke that the mirror will be glued to will be bolted to the mounting ring with a push-pull collimation bolt setup. My friend Cullen Bennett machined this for me in his home based machine shop. This photo was taken 6 April 1999 with an Olympus D-600L digital camera.
