TS-Optics 10" f/7.9 RC Ritchey-Chrétien Telescope (focuser optional)

RC telescopes from TS-Optics are made for astrophotographers. High-quality images of galaxies and nebulae with perfect stars to the edge are possible without additional correctors. At the same time, the image is brighter and contrastier than, for example, the one of a Schmidt-Cassegrain with corrector. Professionals use RC telescopes and now this telescope type is also at your disposal.

The advantages of the TS-Optics RC Telescopes at a glance:

♦ Hyperbolic primary and secondary mirror for a large fully corrected field of view.
♦ Astrophotography with camera sensors up to full-frame size possible without corrector. For larger sensors, we offer ready-to-use corrector solutions.
♦ 99% dielectric high-reflectivity coating on main and secondary mirror for an even brighter image.
♦ Significantly shorter cooling down time through open construction and active primary mirror ventilation.
♦ Internal baffles in the tube for even more contrast.
♦ Long back focus for correctors, reducers and also binoviewers.
♦ Configure your RC with the right (optional) focuser and optimize the telescope for your spectrum of tasks.

Astrophotography with the TS-Optics 10" RC telescope:

Better and sharper astro images without corrector with shorter exposure times. Exactly that is made possible by using this RC telescope with astro cameras and SLR cameras up to full-frame size sensors. As a pure mirror system, you can even use infrared light. You can achieve up to 25% shorter exposure times and a sharper image than, for example, a comparable Schmidt-Cassegrain telescope. With the focal reducer CCD47, you can even increase the focal ratio to fast f/5.29.

Spacers for the ideal back-focus are supplied. You don't need extension tubes, thanks to the spacers, the focuser is always in an optimal position, whether you observe or photograph.
Even large camera sensors up to full-frame size can be used. Even without corrector, sharpness in the field is already very good. With the RC correctors, developed by Teleskop-Service, it becomes even better.

Configure your RC with the focuser of your own choice:

Above all, we recommend two focusers of our TS product range. They directly fit to the M117 thread of the tube.
TSLPR3 - the economically priced 3" Monorail standard focuser We recommend this focuser for visual observing and for medium-sized photo equipment like, for example, DSLR cameras.

The focuser already provides all prerequisites, like dual speed and a bearing which is superior to simple Crayford focusers. We recommend the focuser for accessories up to approx. 4 kg.

TSFOCR30S 3" rack and pinion focuser for heavy accessories We recommend the focuser to all astrophotographers who use heavy equipment. The drawtube is moved by a helical gear. Thus more accuracy and sensitive adjustment are possible even with maximum load.

The focuser supports accessories up to 6 kg without tilting. Optional motor focus, 360° rotation and thread at the camera side are a given.

Astrophotography with the RC telescope:

Due to the large corrected field of view, you can, for example, use a DSLR up to APS-C format without corrector. Thus the RC is a pure mirror system for astrophotography. The images become ultrasharp.

The generous back-focus also allows attaching correctors which we recommend when using sensors of at least full-frame size. You can also attach a focal reducer, thus further increasing the speed of the RC.

♦ Using an SLR without focal reducer: you need a 50 mm and a 25 mm extension tube between focuser and telescope (item # GSRCV50 and GSRCV25).
♦ Using an SLR with focal reducer CCDT67 or CCD47: in this case, a 50 mm extension tube between focuer and telescope (item # GSRCV50) is sufficient.

SPECIAL OFFER 0.67x CCD reducer for astrophotography at a special price

The CCD47 improves the focal ratio from f/7.9 to f/5.29, thus reducing the exposure time to less than 50%. With this, you can capture dim nebulae and galaxies with moderate exposure times.

Save lots of money! When purchasing this RC telescope and the CCD47 directly from 365Astronomy at the same time, you get the reducer at a special price. Of course, the promotional article CCD47 is an absolutely new part with full warranty. -- More information about the CCD47

Primary and secondary mirror of quartz glass with 99% reflectivity and protective dielectrical quarz layer:

Quartz glass does not change its dimensions if temperature changes. When the temperature changes slowly during an exposure, other mirror substrates, like Pyrex, tend to a deformation of the mirror and thus to a shift of the focus. This problem does not exist for mirrors of quartz glass. Thus the focus is better maintained which is very important for long exposures. Both mirrors are coated with 99% reflectivity. The image is obviously brighter than the one of telescopes with only 90% or 94% reflection layer.

The advantages of TS RC telescopes for astrophotography:


The TS RC astrographs are true Ritchey-Chrétien telescopes. Maksutovs and Schmidt-Cassegrains have spherical mirrors and need correctors for making a large field usable. With Schmidt-Cassegrains, you can see the aberrations in the field even when working visually. Most times, Maksutov-Cassegrains are so slow that they are not suitable for astrophotography. RC telescopes have hyperbolical primary and secondary mirrors. They are more difficult to manufacture, but offer a significantly sharper field with less aberrations throughout the field.

Why is the RC Telescope superior to Schmidt-Cassegrain telescopes with correctors:

Celestron EHD or Meade ACF telescopes need a corrector. Additionally, these telescopes have a Schmidt plate at the front side which is prone to dew. The RC is a pure reflection system without lenses in the light path. Thus you can use the complete light even in the infrared range. The image is brighter and the exposure times get shorter. The field of an RC telescope is coma-free by design and relatively flat.

No shifting problem with TS RC telescopes:

Telescopes with focusing via movable primary mirror often suffer from the "shifting problem". The image shifts while focusing or even jumps. By now, Meade and Celestron have the problem under control, but the effect is noticable nonetheless. TS RC telescopes do not have this problem, as their primary mirror is fixed. Focusing is done via a high-quality focuser. An additional advantage is the optimal distance from primary to secondary mirror. This gives you the guarantee of the best possible image. If the primary mirror moves relatively to the secondary, you will practically never have the optimal distance.
