12.5" D-K OTA $8,950
Four are now sold and I'm holding it there

We are tooling up for a first run of 12.5" f/20 D-Ks to be delivered this fall and winter. OTA will be an attractive, solid and light-weight Surrier truss design. All aluminum construction. Comes with curved spider, right-angle finder and Moonlight focuser. --- As soon as the first one is produced it will be photographed and shown on these pages.

Here! A new design for an 8" f/8 Newtonain
*** First Observing Report

Coming The Two Weekend 8" f/6 Telescope

Complete plans and instructions for making two optimized Newtonians. At present, a prototype is virtually completed for an 8" f/8 open Surrier truss tube Newtonian and pictures are available. While the f/8 is a more advanced project, later I will make an 8" f/6 closed tube Newtonian that you can make in two weekends with the simplest of tools and a minimum of experience. And these will be excellent telescopes embodying all of my latest design ideas about high-performance reflectors that will challenge any refractor.

NEW! We make Off-axis, Unobstructed Optical Collimators and Beam Expanders 

Off-axis, unobstructed optical collimators and Beam Expanders for science and industry are now available, and, due to our unique design and manufacturing techniques, they can be made larger and offered at prices considerably below those customarily encountered. Read More
