TS-Optics GSO 14″ RC Pro Carbon Truss Gen.2 355/2854 - The observatory astrograph

Visit TS-Optics GSO 14″ Ritchey-Chrétien (355 mm, 2854 mm, f/8) with carbon truss tube and improved Gen.2 focuser is a powerful instrument for demanding observatories and astrophotographers. Its large diameter, optimized mechanics and exceptional stability make it a top-of-the-range solution for deep-sky imaging.

Highlights

• Genuine Ritchey-Chrétien : primary/secondary hyperbolic → flat, coma-free field.
• Large diameter 355 mm theoretical resolution of 0.34″ and enormous light gathering.
• Quartz mirrors Stability of focus on long exposures despite temperature variations.
• Coating 94 % brighter, higher-contrast image than standard 90 %.
• Carbon truss tube : structural rigidity + low expansion → stable collimation and focus.
• Primary ventilation : faster heat-up, less internal turbulence.
• Two Losmandy dovetails robust mounting of any accessory or guidescope.
• Focuser RAP Gen.2 : rack + steel rail on bearings, high capacity, increased precision, tilt adjustable independently of primary.

Astrophotography

The 14″ RC illuminates a corrected field of around 35 mm without a corrector, ideal up to the APS-C. For the full format and beyond (~70 mm max. with dedicated corrector), TS offers optimized solutions. Thanks to the CCD47 reducer 0.67×the focal length increases from 2854 mm to ≈1913 mm, and the ratio of f/8 to f/5.36This has halved exposure times and widened the field of view.

Why a carbon truss tube?

Carbon virtually eliminates focus drift due to thermal variations. The design truss lightens the assembly, promotes cooling and maintains collimation in all orientations. The 30 kg tube is compatible with compact domes thanks to its limited length (~1 m).

RAP Gen.2 focuser

Visit RAP 3″ Gen.2 significantly improves rigidity and precision: steel rail with bearings, gear rack (1:10), 360° rotation, high load capacity. Multiple integrated threads (M69, M74, M77, M82) for adapters, correctors and OAGs. Compatible with EAF-type focus motors without adapters.

RC vs SCT/Mak advantages

• No Schmidt blade no fogging, no absorption → total transmission (visible + IR).
• Optical path 100 % reflective spectral neutrality and photon gain.
• No mirror shift : fixed primary, MAP via external focuser → maximum stability.
