Ritchey-Chrétien TS-Optics 10" f/6.4 scope with flattener - Carbon Truss
RC Telescope TS 10" f/6.4 photo-optimized with Carbon Truss Tube
An exciting instrument is offered for the dedicated astrophotographer with this Ritchey-Chrétien telescope. The telescope is built by GSO for TS to our specifications. We selected very good optics for this series and used a better focuser. An essential part of the astrograph is the full frame format corrector, which is integrated in the focuser. The corrector is specially designed for RC telescopes and offers a very good field correction for sensors up to full frame format. This gives you a fully equipped telescope for high-resolution astrophotography, which does not have to shy away from comparison with much more expensive instruments.
The mechanics: Taiwanese quality
The mechanics of these modern telescopes form the basis for successful astrophotography. The primary and secondary mirrors are stably mounted and maintain collimation even during telescope rotation. The support elements are made of carbon, which reduces dead weight and improves focusing stability, since carbon does not react to temperature changes as strongly as metal. The focuser can be tilted independently of the primary mirror, a distinctive feature of high-quality RC telescopes. This makes it possible to obtain perfectly round stars even in the very last corner.
The optics of the RC astrograph:
The hyperbolic primary mirror and the secondary mirror are made of quartz glass and have a 94% coating. This makes the image brighter and richer in contrast. Each RC is tested before being converted into a photographic RC in our workshop. The primary focal ratio of the RC is f/8. The RC corrector and reducer improve the focal ratio to f/6.4. The 3-element corrector used is designed specifically for RC telescopes and is not a simple compressor. The result is much sharper stars across the entire field of view.
Working distances for astrophotography:
The photooptimized RC already comes with the proper adaptation for your camera. Of course, the cameras are screwed on and not clamped.
Working distance of 55 mm from the M48x0.75 thread: With the optional T-adapters, this facilitates the connection of astro cameras, system cameras and SLR cameras. The adapter from the M68x1 thread of the focuser to M48x0.75 is already included in the scope of delivery.
Working distance of 73.7 mm from the M68x1 male thread: This connection is suitable for all astrophotographers who prefer an individual adaptation and who may wish to use an off-axis guide. Of course we offer the corresponding articles, a large part is also linked.

RC telescopes are very suitable for astrophotography. Here you can find some astrophotographs made with this telescope model: Link to Astrobin
Visual use of the TSRC10T64:
Although the RC is primarily intended for photographers, observation is of course also possible. Simply unscrew the insert with the focuser corrector and replace it with a 2" insert. The conversion will only take a few minutes and you will have a classic RC telescope for lunar and planetary observation or photography. The 2" insert and 1.25" reducer are of course included.
This is how the RC from TS-Optics is delivered to the amateur astronomer:
- Each RC is sent to our technical department before it is stored. There it is thoroughly checked and optimized. Only Ritchey-Chrétiens that meet our strict guidelines are stored.
- Cosmetic check (dust, scratches, etc.)
- Mechanical check (focuser adjustment, check of all screws)
- Collimation on our optical bench
- Creation of a checklist
Telescope adjustment
RC We recommend the TSRCKOLLI or a collimating telescope to adjust the telescope. These tools are linked in the "Cleaning and collimation" section.
