With Omegon Ritchey-Chrétien telescopes, your astrophotography will reach the next level of quality. Omegon RC telescopes offer a wide field of view free from coma, so you can enjoy perfectly round stars even at the edges of the image. Discover why RC telescopes are the perfect solution for astrophotographers and the first choice for professionals.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvantages at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHyperbolic mirrors: extremely sharp images and a large field of view without correctors\u003c\/li\u003e\n\u003cli\u003eBK7 mirrors: greater focus stability without the need for readjustment\u003c\/li\u003e\n\u003cli\u003eHigh reflectivity: dielectric coating with 92-94% reflectivity for clear, contrast-rich observations and astrophotographs\u003c\/li\u003e\n\u003cli\u003eFast cooling thanks to the open design\u003c\/li\u003e\n\u003cli\u003eElectric fan for even more immediate cooling (10\" version only)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eHyperbolic mirror for better image quality\u003c\/b\u003e\u003cbr\u003eRC telescopes are equipped with hyperbolic primary and secondary mirrors, not spherical mirrors, like Schmidt-Cassegrain systems. This great idea provides an advantage: you will achieve better, sharper astrophotographs in a wider usable field of view! Ultra-sharpness is guaranteed thanks to APS-C sensors, even without a corrector. This technology was barely affordable until a few years ago. But now, Omegon's new RC telescopes are within reach of any astronomy enthusiast.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePhotos without a corrector\u003c\/b\u003e\u003cbr\u003eUse your astronomy camera or DSLR directly with your telescope. You no longer need a corrector to achieve perfectly round, coma-free star photos even at the edges. 6\" RCs are compatible with APS-C format sensors, such as those found in Canon EOS or similar cameras. With 8\" and 10\" models, you can even use FullFrame 24x36 mm sensors without a corrector. In addition, you can also use professional DSLR cameras and countless astronomy cameras. And if you want to take medium format photographs, do not hesitate to ask us about the appropriate resolution.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSteel tube for greater focus stability and contrast\u003c\/b\u003e\u003cbr\u003eApart from mirror quality, the steel tube also plays a fundamental role in taking good astrophotographs. Compared to an aluminum tube, this Omegon RC reduces defocus by 50%. In addition, strategically placed baffles help to increase contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBetter image quality than with SC telescopes\u003c\/b\u003e\u003cbr\u003eRC telescopes are essentially completely different from SC or Maksutov telescopes. They are open systems without a corrector plate that adjust to ambient temperature much faster than SC telescopes. Furthermore, by not having a plate at the front, these telescopes capture clearer images without the risk of reflections. Ritchey-Chrétien systems are the most highly corrected double-mirror telescopes available. The sharpness of the field of view, including the edges, is impressive. So it's no surprise that virtually all large research telescopes in professional observatories use this type of optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnd now within everyone's reach\u003c\/b\u003e\u003cbr\u003eThe manufacture of hyperbolic mirrors is both a science and an art. Until a few years ago, RC telescopes were among the most expensive in the world and were only found in international research institutions. However, today this technology is also affordable for experienced amateur astronomers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581585187159,"sku":"85447","price":704.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/85447_1.jpg?v=1779016027","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/carbon-full-tube-ritchey-chretien-pro-rc-154-1370-ota","provider":"Astro Telescopios","version":"1.0","type":"link"}
