With an 8-inch aperture and premium StarBright XLT coatings, the CGX 800 HD delivers impressive light-gathering capability while maintaining a compact and manageable design. The EdgeHD optical system is paired with Celestron’s proven StarBright XLT coatings to provide a high-performance optical platform for exploring the night sky. With its 8-inch aperture, the CGX 800 HD provides more than 800 times the light-gathering power of the unaided eye, revealing a wealth of celestial targets for detailed observation. As the lightest and most portable telescope in its class, the CGX 800 HD offers an excellent combination of performance and portability. Its computerized equatorial mount provides a capable foundation for astronomers who want advanced telescope functionality without the bulk associated with larger systems.\u003c\/p\u003e\n\u003csection id=\"shopify-section-template--18930283970735__main_product_tabs_K87Yci\" class=\"shopify-section section\"\u003e\n\u003cdiv class=\"tabcontent-container\"\u003e\n\u003cdiv class=\"tab-content-wrapper page-width\"\u003e\n\u003cdiv role=\"tabpanel\" id=\"tab-content-1\" class=\"tab-content\" data-state=\"active\" tabindex=\"0\"\u003e\n\u003cp\u003e\u003cstrong\u003eSee the Universe in HD\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTrue Astrograph Quality\u003c\/strong\u003e\u003cbr\u003eMany optical designs that advertise themselves as \"astrographs\" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.\u003ca href=\"https:\/\/www.celestron.com\/pages\/edgehd-optics\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Performance\u003c\/strong\u003e\u003cbr\u003eSuperior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture.

At its native f\/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f\/2 wide field imaging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIndividually Tested\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eEvery EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance.

Since that time, many more astro-imagers and planetarium controlled setups have emerged as backyard telescope technology has evolved. Celestron’s engineering team applied their years of experience designing German Equatorial mounts to the CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.\u003c\/p\u003e\n\u003cp\u003eThe CGX was designed to better support your telescope for both visual and astro-imaging pursuits. Key design goals included a lower profile EQ head, which provides a more compact and therefore more stable setup; a better drive system; remote operation-friendly with home and limit optical sensors; easier polar alignment adjustments; and better cable management. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our Equatorial backbone to support a wide range of telescopes.\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e8” HD optics\u003c\/li\u003e\n\u003cli\u003eCGX computerized equatorial mount\u003c\/li\u003e\n\u003cli\u003eCelestron’s premium StarBright XLT coatings provide maximum light transmission\u003c\/li\u003e\n\u003cli\u003eA 9x50 finderscope, 1.25” mirror diagonal for more comfortable viewing, and 1.25” 40mm Plössl eyepiece are all included\u003c\/li\u003e\n\u003cli\u003eCelestron’s premium StarBright XLT coatings provide maximum light transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"500\" height=\"300\" src=\"https:\/\/www.youtube.com\/embed\/fmnNr_H9ZQI\" title=\"Introducing the Celestron CGX Computerized German Equatorial Telescope Mount\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":47953417011371,"sku":"CGX 800 EdgeHD","price":3899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/8944\/0683\/files\/12055_cgx_8_edgehd_kit_2.webp?v=1790465796","url":"https:\/\/astronomycity.com\/products\/celestron-cgx-800-edgehd-telescope","provider":"Astronomy City","version":"1.0","type":"link"}
