With Omegon Ritchey-Chrétien telescopes, your astrophotos will reach the next level of quality. Omegon RC telescopes offer a wide visual field free of coma aberration, so you can enjoy perfectly round stars even at the edge 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\u003eSummary of advantages:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHyperbolic mirrors: extremely sharp images and large field of view without correctors\u003c\/li\u003e\n\u003cli\u003eQuartz mirrors: greater focus stability without the need for readjustment\u003c\/li\u003e\n\u003cli\u003eHigh reflectivity: dielectric coating with 92-94% reflection for clear and contrast-rich observations and astrophotos\u003c\/li\u003e\n\u003cli\u003eFast cooling due 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 with spherical mirrors, like Schmidt-Cassegrain systems.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThis great idea offers an advantage:\u003c\/b\u003e you will achieve better, sharper astrophotos in a wider usable field of view! Ultra-sharpness is guaranteed with 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\u003eHyperbolic mirror for better image quality\u003c\/b\u003e\u003cbr\u003eRC telescopes are equipped with hyperbolic primary and secondary mirrors. Not with spherical mirrors, like Schmidt-Cassegrain systems. The RC design is very careful: the optical tube offers a wider field of view and considerably less optical aberration.\u003c\/p\u003e\n\u003cp\u003eImpeccable image quality in a larger field of view: this is the purpose of these telescopes. That's why they are the preferred option for astrophotography. And that's also why RC optical tubes are ideal for CCD cameras, which means you can take sharp photos all the way to the edge without a corrector. This way, you can capture beautiful snapshots of the sky.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePhotos without a corrector\u003c\/b\u003e\u003cbr\u003eUse your astronomical camera or DSLR directly with your telescope. You no longer need a corrector to get perfectly round and coma-free star photos all the way to the edge. The 6\" RCs are compatible with APS-C format sensors, such as those in Canon EOS or similar cameras. In the 8 and 10\" models, you can even use 24x36 mm FullFrame sensors without a corrector. In addition, you can also use professional DSLR cameras and countless astronomical cameras. And if you want to take medium format photographs, do not hesitate to ask us for the appropriate resolution.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQuartz primary mirror\u003c\/b\u003e\u003cbr\u003eIf you have experience in astrophotography, you have probably experienced the focus getting out of alignment during long exposures. It's very annoying! The advantage of this model is that it has 2 quartz mirrors. It hardly expands thermally, so it produces fantastic images and maintains focus throughout the night.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSteel tube for greater focus stability and contrast\u003c\/b\u003e\u003cbr\u003eApart from the quality of the mirror, the steel tube also plays a fundamental role in taking good astrophotos. Compared to the aluminum tube, this Omegon RC reduces blur by 50%. In addition, strategically placed scattered light baffles contribute to increasing contrast.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBetter image quality than with SC telescopes\u003c\/b\u003e\u003cbr\u003eRC telescopes are, in essence, 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. In addition, 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 wonder that practically 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 a science and an art. Until a few years ago, RC telescopes were some of 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":53581585219927,"sku":"85448","price":1290.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/85448_1.jpg?v=1779016029","url":"https:\/\/astrotelescopios.com\/en-eu\/products\/carbon-full-tube-ritchey-chretien-pro-rc-203-1624-ota","provider":"Astro Telescopios","version":"1.0","type":"link"}
