Omegon Ritchey-Chretien telescopes will take you to the next quality level with your astronomy photos. Omegon RC telescopes provide a wide, coma-free field of view - perfect for round stellar images right out to the edge of the field of view. Find out exactly why an RC telescope is the right choice for astronomy photography and why the professionals also use them.  The advantages in a nutshell   hyperbolic mirrors - extremely sharp image, wide field of view, with no need for a corrector  BK7 mirrors for stable focus, for stable focus without the need to refocus  high reflection - 92-94% dielectric reflective coating for bright, high-contrast observing and astronomy photos  rapid cool-down thanks to open design  electric fans for even faster cool-down (only for 10\" model)  &nbsp;  &nbsp;  Hyperbolic mirrors for a better image RC telescopes have hyperbolic main and secondary mirrors. They do not use spherical mirrors, such as in Schmidt-Cassegrain systems. This great idea gives you a big advantage - take better and sharper astronomy photos and enjoy a wider usable field of view! Ultra-sharp with APS-C chips. even without using a corrector. This technology was unaffordable even a few years ago, but the new Omegon RC telescopes are now affordable for every amateur astronomer.  Photograph without needing a corrector Use your DSLR or astronomy camera with your telescope without needing a corrector, for coma-free and pin-sharp stellar images, right out to the edge of the field of view. The 8\" and 10\" models even allow you to use 24x36mm full-frame chips without any corrector. All professional DSLR cameras will fit and countless astronomy cameras too. And, if you still want to photograph in the medium format, please do not hesitate to ask us for appropriate solutions.  Steel OTA for stable focusing and high contrast In addition to containing a good mirror, a steel OTA plays a decisive role in producing good astronomy photos. This Omegon RC OTA has a 50% reduced focus shift when compared to an aluminium OTA. Precisely located stray-light baffles also ensure high contrast.  A better image than an SC telescope To start with, an RC telescope is completely different to the classic SC or Maksutov design. It has no corrector plate and is hence an open system that adapts faster to the ambient temperature than an SC telescope. The absence of a front corrector plate also means that the telescope provides brighter images with no risk of internal reflections. Ritchey-Chretien systems are the most highly corrected two-mirror telescopes available. Their edge-to-edge image sharpness is impressive, so it is no wonder that practically all large research telescopes use this design of telescope in their professional observatories.  Now affordable Making hyperbolic mirrors is both a science and an art. Up to only a few years ago, RC telescopes were among the most expensive telescopes in the world - only international institutions used them for research. But this technology is also now also affordable for experienced amateur astronomers.          The 6\" RC telescope weighs 5.5 kilograms and is best used on a medium-sized mount.        The 6\" RC telescope with the 44mm Vixen style rail fits on almost any mount for astrophotography.        Use the spacers to adjust the focus position accordingly when using your own accessories.
