13.1" F4.5 Telescope for
John T., Jackson MI.

John T's 13.1" F4.5 optical tube assembly (OTA) is virtually complete. I need only attach the alt bearings and finish the rocker box. My goal is to complete the telescope by the end of this week.

Note this telescope has the "ETT" option. The Easy Transport Telescope option has 1/2 the length of the struts with a reinforcing intermediate ring to add rigidity. The struts are 51.5" long (each of the 6 smaller struts is 25.75" long for "easy transport").
