Description

Next night take it to the next level - Omegon RC telescope for astrophotographers

Are you looking for an excellent telescope for astrophotography? 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. Discover exactly why an RC telescope is right for astronomy photography and why the professionals use them too.

The advantages in a nutshell:

  • hyperbolic mirrors - extremely sharp image, wide field of view with no need for a corrector
  • quartz mirrors for stable focus, eliminating 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)

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 is a big advantage to you - 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. 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.

Quartz main mirror

You have probably experienced this yourself if you are an experienced astrophotographer - focus drift during long exposures. This is extremely annoying! The advantage with this model is its two quartz mirrors - these undergo virtually no thermal expansion and so provide not just a fantastic image but, once focused, will remain focused for the entire night.

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.

Large unobstructed aperture: 3” focuser

The back end is especially important: the bearing-mounted 3” Linear Crayford Focuser gives you enough space to illuminate even large format image fields without vignetting.

A hybrid of Crayford and guide rail offers you the effortlessness of a Crayford focuser with the stability of a good rack and pinion focuser.

  • Always the perfect object alignment: focuser is completely rotatable
  • Reducer from 2” to 1.25” with integrated compression ring
  • Fine adjustment for the perfect focus: 1:10 reduction for minimal focus setting
  • Setting scale so you can quickly find your focus again
  • Highly stable: no movement so the camera remains perfectly aligned to the optical axis and the picture remains sharp

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.
