All updates have been performed on this telescope. No telescope type has changed the hobby quite as much as the Dobsonian. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars.

This has made it possible to produce this 20\" lightweight Dobsonian incredibly stiff despite its low weight.\u003cbr\u003e\u003cbr\u003eThe Dobsonian comes with a second 40° displaced installed mounting plate with a viewfinder shoe, allowing for the rotation of the tube top in combination with a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The six supporting feet underneath the rocker box offer perfect stability and guarantee smooth tracking in azimuth. Four smaller fans and a large fan under the main mirror allow for quick adaptation to ambient temperature and reduce tube seeing (boundary layer removal). The lateral altitude wheels can comfortably be stowed in the foam layers of the mirror box.\u003cbr\u003e\u003cbr\u003eThe Dobsonian includes a 2.5\" HEX focuser with helical gearing and a 10:1 reduction, an LED Red Dot Finder, a collimation assist tool, a soft light baffle, and two radial main mirror fans for fast temperature equilibrium.\u003c\/p\u003e\n\u003cp\u003eThe scope is ready for

All updates have been performed on this telescope. No telescope type has changed the hobby quite as much as the Dobsonian Telescope. Before the popularization of John Dobson’s altazimuth mount design with low center of gravity combined with a Newtonian optical assembly, the vast majority of amateur telescopes consisted of small telescopes with small mounts - which made them difficult to use for serious deep sky observations by beginners. Large commercial telescopes could certainly do the job but were relatively expensive. The ingenious combination of simple yet effective mechanisms with big-aperture Newtonian optics gives the Dobsonian Telescope worldwide popularity, and this telescope design typically offers the largest aperture per dollar of any telescope type. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in very small cars. The entire structure has been optimized for maximum stiffness with minimal weight. The combination of large altitude bearings with optimized metal structural design allows fine and smooth adjustment, even at higher magnifications.The ideal workhorse for the deep sky observers. A 254mm aperture mirror collects more than 1,500 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Many star clusters are resolved to the core, spiral structure in distant galaxies is visible, and the complex matrix of bright and dark nebulae are an unforgettable experience. Oversize altitude (16.5-inch) and azimuth (13-inch) bearings allow for smooth operation.

Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson.\u003c\/p\u003e\n\u003cp\u003eNow, Explore Scientific has come up with the ultimate universal design. This Dobsonian can be converted into a Newtonian telescope. If you ever wanted to take pictures, simply unscrew the bearings from the tube and place the scope on an EQ mount with the included Vixen style dovetail plate.\u003c\/p\u003e\n\u003cp\u003eThe unrivaled stiffness of the included 2.5\" HEX focuser makes focusing easy and allows the use of both 1.25\" and 2\" eyepieces. Including the 2.5\" Hex focuser is a quantum leap for this price class of telescope.\u003c\/p\u003e\n\u003cp\u003eA Red Dot viewfinder as well as a 25mm SPL eyepiece are included with the device. If you want to transport the telescope as compactly as possible, the new 10\" FirstLight Dobsonian \/ Newtonian is easy.\u003c\/p\u003e\n\u003cp\u003eThe Rockerbox can be dismantled with a few tools, because the parts are assembled with metal quick connectors. Thus, a bulky rocker box quickly becomes a handy flat package of boards. The ideal workhorse for the deep sky observers. Details on planets and deep sky objects will be visible even for inexperienced observers. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience.\u003c\/p\u003e\n\u003cp\u003eThe scope is ready for use with our optional coma corrector.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCA Residents: \u003c\/span\u003e\u003cstrong\u003e\u003ca rel=\"noopener\" aria-label=\"Prop 65 WARNING(S) - Opens in a new tab\" href=\"https:\/\/explorescientificusa.com\/pages\/prop65\" target=\"_blank\"\u003eProp 65 WARNING(S)\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch6\u003eSPECIFICATIONS:\u003c\/h6\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eItem Number\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eFL-DOB0806-02\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eSecondary Obstruction\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e24%\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003ePrimary Mirror Diameter\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e203mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal Length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e1218mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal Ratio\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003ef\/6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003ePrimary Tube Weight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e25 lbs\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eRocker Box Weight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e21 lbs.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal Weight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e46 lbs\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch6\u003eWARRANTY:\u003c\/h6\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eExplore Scientific Limited USA One Year Warranty. \u003c\/span\u003e\u003ca href=\"https:\/\/explorescientificusa.com\/apps\/product-registration\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eClick Here\u003c\/span\u003e\u003c\/a\u003e\u003cspan style=\"font-weight: 400;\"\u003e to register.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003eEXTRAS:\u003c\/h6\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" aria-label=\"Download Manual - Opens in a new tab\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0390\/6029\/files\/FirstLight_Dob_Manual_2018.pdf?13611491345780908637\" target=\"_blank\"\u003eDownload Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":47846883950896,"sku":"FL-DOB0806-02","price":709.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/3113\/5280\/files\/FL-DOB0806-01_1200x1200_e6af2717-eac6-41e6-a45b-a01ec8875f44.jpg?v=1710282097"}],"url":"https:\/\/b9549c-5.myshopify.com\/collections\/dobsonian-telescopes.oembed","provider":"StellarOptix","version":"1.0","type":"link"}
