Tecnosky 115/800 V3 Triplet APO Refractor

Overview

The Tecnosky 115/800 V3 is a high-performance triplet apochromatic refractor designed for deep-sky astrophotography and visual observation. Its air-spaced lens includes Ohara FPL-51 fluorite glass, combined with two high-index elements, offering excellent chromatic correction and contrast.

The redesigned lightweight aluminum tube features internal baffles and a retractable dew shield with lock. It’s paired with a 2.5" rack-and-pinion focuser, providing 80 mm travel and a 1:10 micro reduction—ideal for supporting heavy imaging setups.

The scope is compatible with a 0.8× reducer/corrector for APS-C and full-frame cameras.
