Aperture: 304mm. Focal length: 1525mm\u003c\/p\u003e\u003cp\u003eThe Levenhuk New Skyline PRO 12\" Dobson telescope is a professional instrument for detailed observation, from the Moon and planets to deep-sky wonders such as nebulae, galaxies, and globular clusters.\u003c\/p\u003e\u003cp\u003eIts 304mm aperture and 1525mm focal length provide exceptional light-gathering capability and high resolving power. The internal optical design of the telescope uses BK-7 glass elements. This material is highly valued in the optical industry for its homogeneity and mechanical strength. The primary and secondary mirrors are aluminum-coated, increasing their reflectivity to 92–95%. The parabolic primary mirror corrects spherical aberration by perfectly focusing all light to a single point, ensuring sharp images across the entire field of view. As a Newtonian reflector, this optical system is completely free of chromatic aberration, providing consistently crisp views with true color reproduction.\u003c\/p\u003e\u003cp\u003eDesigned for portability, the telescope uses an open truss tube system. It assembles quickly from sturdy components and stores in minimal space when disassembled. The optical tube is installed on a Dobson base. This mount is stable, robust, and built to last, making the Levenhuk New Skyline PRO 12\" easy and intuitive to operate. The mount is made of processed wood, weighs 16.5 kg, and easily supports the considerable weight of the large optical tube (20.5 kg). The telescope package includes all necessary accessories to start observing right out of the box: an 8x40 optical finderscope, a cooling fan for the primary mirror, two Plössl eyepieces (10mm and 25mm, 1.25\"), and a protective shroud to protect the optical tube components from dust and wind.\u003c\/p\u003e\u003cp\u003eThe telescope is designed for use in temperatures ranging from -5°C to +35°C. The best observation results are obtained in clear atmospheric conditions, on cloudless nights. For optimal performance, allow the optical system to thermally acclimate to outdoor conditions for 1.5 to 3 hours before observing, especially if not using the cooling fan.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003cbr\u003eOptical tube with a fixed open truss design and protective shroud; optical tube weight is 20.5kg\u003cbr\u003eStable Dobson mount with a black finish; made of processed wood\u003cbr\u003eOptical elements are made of BK-7 glass with aluminum coating, with 92–95% reflectivity\u003cbr\u003eSharp, aberration-free images, without spherical or chromatic distortion\u003cbr\u003eIncludes essential accessories: eyepieces, finderscope, protective shroud, and primary mirror cooling fan\u003cbr\u003eThe fan for thermal stabilization operates on 8 AA batteries\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe kit includes:\u003c\/strong\u003e\u003cbr\u003eTelescope optical tube\u003cbr\u003ePlössl 10mm (1.25\") eyepiece\u003cbr\u003ePlössl 25mm (1.25\") eyepiece\u003cbr\u003eOptical finderscope, 8x40\u003cbr\u003ePrimary mirror cooling fan\u003cbr\u003eLight baffle shroud\u003cbr\u003eDobson mount\u003cbr\u003eUser Guide and Warranty Card\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003eOptical design: reflector\u003cbr data-start=\"24\" data-end=\"27\"\u003eOptical system: Newtonian\u003cbr data-start=\"53\" data-end=\"56\"\u003eOptics material: BK-7\u003cbr data-start=\"77\" data-end=\"80\"\u003eOptics coating: aluminum, 92–95% reflectivity\u003cbr data-start=\"143\" data-end=\"146\"\u003ePrimary mirror diameter (aperture), mm: 304\u003cbr data-start=\"195\" data-end=\"198\"\u003eSecondary mirror obstruction, mm: 70\u003cbr data-start=\"239\" data-end=\"242\"\u003eLens shape (mirror): parabolic\u003cbr data-start=\"280\" data-end=\"283\"\u003eFocal length, mm: 1525\u003cbr data-start=\"308\" data-end=\"311\"\u003eHighest useful magnification, x: 600\u003cbr data-start=\"338\" data-end=\"341\"\u003eRelative aperture: f\/5\u003cbr data-start=\"363\" data-end=\"366\"\u003eResolution threshold, arcseconds: 0.46\u003cbr data-start=\"410\" data-end=\"413\"\u003eFocus: manual\u003cbr data-start=\"428\" data-end=\"431\"\u003eEyepieces: Plössl 10mm (153x), Plössl 25mm (61x)\u003cbr data-start=\"480\" data-end=\"483\"\u003eEyepiece barrel diameter, inches: 1.25\u003cbr data-start=\"523\" data-end=\"526\"\u003eBarlow lens: —\u003cbr data-start=\"544\" data-end=\"547\"\u003eFinderscope: optical, 8x40\u003cbr data-start=\"569\" data-end=\"572\"\u003eFocusing system: 2\" rack-and-pinion, dual-speed, includes 1.25\" adapter\u003cbr data-start=\"666\" data-end=\"669\"\u003eTelescope control: manual\u003cbr data-start=\"699\" data-end=\"702\"\u003eMount: Dobson\u003cbr data-start=\"721\" data-end=\"724\"\u003eMount material: wood\u003cbr data-start=\"754\" data-end=\"757\"\u003eMount dimensions, mm: 680x680x606\u003cbr data-start=\"799\" data-end=\"802\"\u003eMount weight, kg: 16.5\u003cbr data-start=\"830\" data-end=\"833\"\u003eOther features: primary mirror cooling fan (included), fan power supply: 8 AA batteries (not included); light baffle shroud (included)\u003cbr data-start=\"1017\" data-end=\"1020\"\u003eOperating temperature range, °C: –5… +35\u003cbr data-start=\"1076\" data-end=\"1079\"\u003eTube material: metal\u003cbr data-start=\"1103\" data-end=\"1106\"\u003eTube dimensions, mm: 1427x365\u003cbr data-start=\"1140\" data-end=\"1143\"\u003eTube weight, kg: 20.5\u003cbr data-start=\"1166\" data-end=\"1169\"\u003eUser level: advanced users, professionals\u003cbr data-start=\"1220\" data-end=\"1223\"\u003eAssembly and installation difficulty level: easy\u003cbr data-start=\"1274\" data-end=\"1277\"\u003eObserved objects: deep-sky objects\u003c\/p\u003e","brand":"Levenhuk","offers":[{"title":"Default Title","offer_id":52888302354775,"sku":"86289","price":2234.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/86289_levenhuk-new-skyline-pro-12-rtb-telescope_00.jpg?v=1776608552","url":"https:\/\/astrotelescopios.com\/en-us\/products\/telescopio-dobsoniano-retractil-levenhuk-new-skyline-pro-12-300-1525","provider":"Astro Telescopios","version":"1.0","type":"link"}
