This astrograph is capable of producing an exposure 6x faster than any f\/10 optical tube.\u003cbr\u003e\nEven pricey refractors have trouble reaching a focal ratio this fast. Using a faster optical tube\u003cbr\u003e\nwill shorten the exposure time, giving you more time to photograph nebulae, clusters, and other\u003cbr\u003e\ndeep sky objects.\u003cbr\u003e\nLike all Sky-Watcher reflectors, our Quattro Imaging Newtonian features aluminum-\u003cbr\u003e\ncoated borosilicate mirrors with a quartz overcoat, producing 94% reflectivity. The optical\u003cbr\u003e\nsystem uses an oversized secondary mirror, providing greater illumination for DSLRs and CCDs\u003cbr\u003e\nusing full-frame sensors. The optical tube is constructed with rolled steel, and features Sky-\u003cbr\u003e\nWatcher’s signature metal-flake Black Diamond finish on the exterior. The interior of the optical\u003cbr\u003e\ntube uses knife-edge baffles to absorb any stray light from ruining your images.\u003cbr\u003e\nAs customary with all Sky-Watcher telescopes, a boat-load of accessories are bundled\u003cbr\u003e\nwith the optical tube. First is a 2-inch dual-speed 10:1 focuser with included 1.25-inch eyepiece\u003cbr\u003e\nadapter, which provides flexibility for either 1.25-inch or 2-inch eyepieces. Also included are\u003cbr\u003e\ntube rings and a V-style dovetail plate, as well as a 9x50 finderscope. For photographers\u003cbr\u003e\nlooking to create a flat field and eliminate vignetting, an optional coma corrector is available\u003cbr\u003e\nseparately. Parabolic mirrors normally produce some aberrations around the edge of the field of\u003cbr\u003e\nview (coma), so this corrector is highly recommended for users with large imaging sensors and full-frame DSLRs.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEAN:\u003c\/b\u003e 0050234112109\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Dimensions:\u003c\/b\u003e 31.5 x 18.0 x 15.5 inches\u003c\/p\u003e","brand":"Sky-Watcher","offers":[{"title":"Default Title","offer_id":47690275881154,"sku":"B00Z4HVSZU","price":1572.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/4101\/4978\/files\/61vIikLfTBL.jpg?v=1779465908","url":"https:\/\/safebuy03.store\/products\/sky-watcher-quattro-200p-imaging-newtonian-large-aperture-8-inch-reflector-optical-tube-for-astrophotography","provider":"Safe Buy03","version":"1.0","type":"link"}
