GSO Newton Truss 254 mm f/4

GSO Newton Truss 254 mm f/4

Overview

The GSO Newton Truss 254 mm f/4 is a high-performance Newtonian telescope tailored for demanding astrophotographers. Its carbon truss structure provides excellent thermal stability, minimizing focus drift during temperature changes.

With a 254 mm primary mirror featuring 94% reflectivity, this telescope delivers bright, high-contrast images, making it ideal for capturing faint deep-sky objects. The 2" Monorail focuser with 1:10 micro-reduction ensures accurate and stable focusing, even with heavy imaging setups.
