Still another project head-start...
OTA Rings for John T. in Jackson ,Michigan.
A set of OTA (optical tube assembly) rings for John T. in Jackson Michigan. I'm building a 13.1" (Coulter primary and secondary) for John with the Easy Transport (ETT) option. The mirror board, on the left, has the beginnings of a 6-point flotation mirror cell with aluminum and Baltic birch components. After building about a dozen of these telescopes, I found this to be a good combination for these mirrors.
