The TS-Optics GSO 10″ Ritchey-Chrétien (250 mm, 2000 mm, f/8) with carbon truss tube is a dream instrument for astrophotography. Designed on the same principle as large professional telescopes, it offers a corrected field of view, exceptional focus stability and robust mechanics suitable for heavy setups.
The 10″ RC allows you to use the sensors up to APS-C with no corrector, delivering razor-sharp images. For the full formatIn order to obtain a perfectly flat field, we recommend the use of an RC corrector. With the CCD47 reducer 0.67×the focal length is reduced from 2000 mm to around 1340 mm, and the f/8 ratio to f/5,36reducing exposure time by more than half, while widening the field of view.
The weight reduction is minimal (~500 g), but the focus stability temperature variations is incomparable. The carbon has virtually zero expansion, guaranteeing long, refocus-free sessions. The truss structure maintains collimation perfectly, whatever the position of the telescope, while facilitating ventilation.
An evolution of the classic Crayford, the 3" Monorail" is based on a solid stainless steel slide, preventing tilt even with heavy optical trains. It features a stroke of approx. 80 mm, a clear aperture of 68 mm, a 1:10 gear ratio for fine adjustment, 360° rotation and dedicated threads (M77x0.75 female, M74x0.75 male, M68 internal) for optimum compatibility (correctors, OAG, heavy cameras).
The TS-Optics GSO 10-inch RC Pro Carbon Truss is a benchmark for deep-sky imaging: wide, corrected field, focusing stability thanks to carbon + quartz, robust mechanics with tiltable focuser and support for heavy optical trains. A telescope designed for the demanding astrophotographer aiming for results worthy of professionals.
With a 250-mm aperture at f/8 and a focal length of 2,000 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.
It can still be transported by car: the tube weighs about 16.5 kg.
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.
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 2000 mm, it requires precise tracking: be sure to use autoguiding for long exposures. With a tube weighing approximately 16.5 kg (without accessories), choose a mount with a load capacity that leaves some margin.
