Product Description

We have combined the venerable 80mm ED doublet optic with our new 2.5" rack and pinion, dual speed focuser to produce the highest quality and most versatile 80ED ever. The hand figured, extra low dispersion doublet will provide sharp high contrast views. The focuser has a higher lifting capacity and is smoother  than import 2" Crayfords. Add to this that one can thread on the photographic field flattener and you have a superb visual and photographic instrument. This telescope is also available in a lightweight carbon fiber tube and dew shield.

The SV80ED has a lightweight aluminum tube and dew shield. It weighs only 4.8 pounds without the ring, 6.4 pounds with it. It comes with a cnc clamshell ring, flat mounting base with three 1/4-20 threaded holes, 2.5" Stellarvue rack and pinion, dual speed focuser with 2" and 1.25" compression ring adapters.
