Περιγραφή

Ritchey-Chrétien Pro RC Telescope 8" (only tube)


Most large professional telescope are constructed according to the RC principle. Until recently, these telescopes were unaffordable for amateurs. RC telescopes from Teleskop-Service are primarily aimed to amateur astronomers with photographic interest. These telescopes are perfectly suited for high-resolution astrophotography. Of course, an RC can also be used for visual observing. Here, the large corrected field of view is noticeable, too. In total, the stars are sharper than, for example, in a Schmidt-Cassegrain.

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 30 mm diameter possible without corrector. For larger sensors, like full-frame size, Teleskop-Service offers 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
♦ Internal baffles in the tube for even more contrast.
♦ High back focus for correctors, reducers and also binoviewers.
♦ High-quality 2" MONORAIL focuser with 2" and 1.25" receptacle.

 

Astrophotography with the TS-Optics 8" 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 APS-C sensors. As a pure mirror system, you can even use the 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/5.36.

Spacers for the ideal back-focus are supplied. You don´t need extension tubes, thanks to the spacers, the focuser is allways 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.


The 2" MONORAIL focuser - more than a Crayford:


The Monorail focuser combines the ease of movement of a Crayford focuser with the stiffness of a rack-and-pinion focuser. Thus astrophotography becomes a success.

♦ Massive stainless steel bar instead of small ball bearings for more stiffness.
♦ No tilting anymore when locking the drawtube.
♦ 360° rotation for optimal object alignment
♦ Female M69x1 thread for threaded adaptions
♦ 2" and 1.25" compression rings for push adaptions
♦ 1:10 dual speed for accurate focusing
♦ Motor focus can easily retrofitted
♦ Lined scale for quick retrieving of the focus.
♦ Easy operation
