A customer recently called because his vintage Tele Vue Renaissance telescope needed some tender-loving care. The Renaissance was our second model, put on the market after the 1981 “Multi-Purpose Telescope” (MPT). The customer’s scope was built in 1985 and is from the initial production design with a bolt-on focuser. After discussing the obvious issues that needed addressing and our evaluation process, he decided it would be worth it to him for us to have a look at the scope.
When we received the scope, the most obvious troubling issue was the focuser. It was unusable. The pinion shaft was badly bent and two of the three teflon runners supporting the draw-tube along its travel were missing. The outer surface of the objective showed years of grime, and all of the brass components were heavily oxidized. The optics, however, were only slightly mis-aligned, producing a mildly flaired star shape at high power, but the image was still serviceable for terrestrial and deep sky viewing. Sadly, after a complete optical and mechanical inspection, we concluded that it just wasn’t worth the effort and expense to revive the telescope. That, however, was not our customer’s conclusion.
He gave us the go-ahead and we proceeded to give his 1985, brass Tele Vue Renaissance a new lease on life. A “renaissance” for this Renaissance if you will!
