Tecnosky Triplet APO 130/900 LT Refractor

Tecnosky Triplet APO 130/900 LT Refractor

Overview

The Tecnosky Triplet APO 130/900 LT is a high-end apochromatic refractor using a carefully selected triplet combination: FPL-51, Lanthanum, and ED glass. This optical design delivers outstanding chromatic correction, even on bright targets, and is well suited for full-frame astrophotography.

The updated OTA features a more compact and lightweight build, improved thermal stability, and an internally baffled tube for contrast optimization.

At the rear, a massive 3.7" rack-and-pinion focuser with 1:10 micro adjustment and an integrated field rotator can hold up to 7 kg. The back threads (M100x1, M92x1, M68x1) support various flatteners and accessories.

Compatible with Tecnosky 1x, 0.8x, and 0.72x field correctors, it can be adapted for f/7, f/5.5, or f/5 operation, with full-frame coverage.
