Just completed a "full" kit for Kevin on the island of Guam. The kit includes all the components for a 16" truss telescope -- mirror, secondary, spider, secondary focuser and 18-point flotation mirror cell. It turns out the only way to get this kit to Guam is via the United States Post Office!! After checking with Fed Ex and U.P.S. -- and their costs were $1000 and more, the USPS delivers to that part of the world for just a couple of hundred dollars..

Just completed is a 16" F4.5 for Joe in Palos Verdes California. The mirror, mirror cell, secondary and spider were from Joe's 16" Lightbridge. The focuser is a Moonlite 2-inch 2-speed Crayford. Yet to be added is a Telrad.
The rear detail of the optical tube assembly. You can see the 27-point flotation mirror cell and cooling fan.
Here's the detail of the top ring. The Telrad is mounted on a short strut just to the right and above the eyepiece. A 2.50# sliding counterweight, just visible at the bottom of the photo, helps keep the tube in balance when changing eyepieces.
The mirror box sitting in the rocker box during assembly. The altitude encoder is affixed to the bearing side.
The azimuth encoder is installed on the rocker box. Joe uses an Argo Navis digital setting circle.
