TS-Optics GSO 14″ RC Pro Carbon Truss Gen. 2 355/2845 – The Observatory Astrograph

The TS-Optics GSO 14-inch Ritchey-Chrétien (355 mm, 2,845 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 covers a corrected field of approximately 35 mm without a corrector, ideal up to 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 changes from 2,845 mm to ≈1,906 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

The 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.

In the box

  • RC 14″ f/8 Carbon Truss Telescope, Gen. 2
  • Focuser RAP 3″ Gen. 2
  • Two Losmandy dovetails
  • Extension rings (2×25 mm, 1×50 mm)
  • Protective cap

In a nutshell

The TS-Optics GSO 14″ RC Pro Carbon Truss Gen. 2 is designed for private or community observatories: 355 mm diameter, reinforced mechanics, tilt-adjustable focuser, thermal stability and corrected wide field. A robust, scalable platform for professional-level results in advanced astrophotography.

Frequently asked questions

Frequently asked questions

What can you see with the TS-Optics GSO RC 14″?

With an open aperture of 355 mm at f/8 and a focal length of 2,845 mm, it is primarily an astrophotography telescope: when used with a camera, it is designed to photograph small objects—galaxies, planetary nebulae, and globular clusters—which it displays in great detail.

Is it easy to carry?

It is an imposing instrument: the tube weighs about 30 kg and is about 114 cm long.

Should we aim it at him?

Yes, from time to time: a Ritchey-Chrétien telescope requires precise alignment of its two mirrors, especially after being transported. A collimation tool for a Ritchey-Chrétien telescope makes it easier to adjust, and you can then fine-tune it using a star.

Can we take pictures?

Yes, that's what it's designed for: it mounts on a motorized equatorial mount (not included) with an astro camera or a regular camera. At f/8 and a focal length of 2845 mm, it requires precise tracking: be sure to use autoguiding for long exposures. With a tube weighing about 30 kg (without accessories), choose a mount with a load capacity that leaves some margin.
