Next night, next level: Omegon RC telescope for astrophotographers

Are you looking for a good telescope for astrophotography? Enter the next level of quality for your astrophotos with the Omegon Ritchey Chretien telescopes. The Omegon RC telescopes offer you a large and comfree field of view. Perfect for round stars to the edge. Find out why an RC telescope pays off for the astrophotographer and why the pros also use it.

The advantages at a glance:

Hyperbolic mirrors: extremely sharp image, large image field without correctors
Mirror from BK7 for stable focus, refocusing is no longer necessary
High Reflection: 92-94% dielectric mirroring for bright, high-contrast observations and astrophotos
Fast cooling time, thanks to open design
Electric fans for even faster cooling time (only with 10 "version)
3x extension sleeves already included 2x 25mm, 1x 50mm

Hyperbolic mirrors for a better picture:

The RC telescopes have hyperbolic main and secondary mirrors. No spherical mirrors, as in Schmidt-Cassegrain systems. This great idea will be to your advantage: Better and sharper astrophotos with a larger usable field! For APS-C chips even without corrector ultra-sharp. Until a few years ago, this technique was hardly affordable. The new Omegon RC telescopes are now available to any amateur astronomer.

Photograph without corrector:

Use your DSLR or astro camera on your optics. You do not need another proofreader, for comfree and needle-fine stars to the edge. In the 6 "RC chips in APS-C format can be used, for example, a Canon EOS or similar In the 8" and 10 "models you even use FullFrame chips with 24x36mm without any correction.All fit professional DSLR cameras and countless astro cameras, and if you still wish to photograph in medium format, ask us for the right solution.

Steel tube for stable focus and high contrast:

In addition to a good mirror, the tube made of steel plays a decisive role for good astrophotos. Compared to an aluminum tube, this Omegon RC has a 50% reduced focus shift. Exactly set stray light panels also provide a high contrast.

Better picture than with a SC telescope:

First, an RC telescope is designed completely differently than a classic SC or Maksutov telescope. Without a correction plate, it is an open system that adapts to the ambient temperature faster than an SC telescope. Due to the missing plate at the front, the telescope also achieves brighter pictures without the danger of reflections. Ritchey-Chretien systems are the most highly corrected two-mirror telescopes. The field and edge sharpness is impressive. So it is no wonder why practically all major research telescopes in the professional careers use these optics.

Now they are affordable
Making hyperbolic mirrors is a science and an art. Until a few years ago, the RC telescopes were therefore among the most expensive telescopes in the world. Only international institutes used them for research. But now this technique is also available for experienced amateur astronomers.
