TS-Optics GSO 14\u2033 RC Pro Carbon Truss Gen.2 355\/2854 - The observatory astrograph<\/h3>\n

Visit TS-Optics GSO 14\u2033 Ritchey-Chr\u00e9tien (355 mm, 2854 mm, f\/8)<\/strong> with carbon truss tube<\/strong> and improved Gen.2 focuser<\/strong> 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.<\/p>\n

Highlights<\/h3>\n
    \n
  • Genuine Ritchey-Chr\u00e9tien<\/strong> : primary\/secondary hyperbolic \u2192 flat, coma-free field.<\/li>\n
  • Large diameter 355 mm<\/strong> theoretical resolution of 0.34\u2033 and enormous light gathering.<\/li>\n
  • Quartz mirrors<\/strong> Stability of focus on long exposures despite temperature variations.<\/li>\n
  • Coating 94 %<\/strong> brighter, higher-contrast image than standard 90 %.<\/li>\n
  • Carbon truss tube<\/strong> : structural rigidity + low expansion \u2192 stable collimation and focus.<\/li>\n
  • Primary ventilation<\/strong> : faster heat-up, less internal turbulence.<\/li>\n
  • Two Losmandy dovetails<\/strong> robust mounting of any accessory or guidescope.<\/li>\n
  • Focuser RAP Gen.2<\/strong> : rack + steel rail on bearings, high capacity, increased precision, tilt adjustable independently of primary.<\/li>\n<\/ul>\n

    Astrophotography<\/h3>\n

    The 14\u2033 RC illuminates a corrected field of around 35 mm without a corrector, ideal up to the APS-C<\/strong>. For the full format<\/strong> and beyond (~70 mm max. with dedicated corrector), TS offers optimized solutions. Thanks to the CCD47 reducer 0.67\u00d7<\/strong>the focal length increases from 2854 mm to \u22481913 mm, and the ratio of f\/8 to f\/5.36<\/strong>This has halved exposure times and widened the field of view.<\/p>\n

    Why a carbon truss tube?<\/h3>\n

    Carbon virtually eliminates focus drift due to thermal variations. The design truss<\/strong> 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).<\/p>\n

    RAP Gen.2 focuser<\/h3>\n

    Visit RAP 3\u2033 Gen.2<\/strong> significantly improves rigidity and precision: steel rail with bearings, gear rack (1:10), 360\u00b0 rotation, high load capacity. Multiple integrated threads (M69, M74, M77, M82) for adapters, correctors and OAGs. Compatible with EAF-type focus motors without adapters.<\/p>\n

    RC vs SCT\/Mak advantages<\/h3>\n
      \n
    • No Schmidt blade<\/strong> no fogging, no absorption \u2192 total transmission (visible + IR).<\/li>\n
    • Optical path 100 % reflective<\/strong> spectral neutrality and photon gain.<\/li>\n
    • No mirror shift<\/strong> : fixed primary, MAP via external focuser \u2192 maximum stability.<\/li>\n<\/ul>\n
