Its hybrid design combines a solid-tube upper assembly - protecting the secondary mirror from dust and stray light - with the lightweight, tool-free truss tube structure that makes setup fast and transport simple. The massive 254mm (10-inch) primary mirror pulls in enough light to reveal faint galaxies, nebulae, star clusters, and crisp lunar and planetary detail that smaller instruments simply can't match.\n\u003c\/p\u003e\n\u003cp\u003e\n  Whether you're a dedicated backyard observer or a serious amateur astronomer heading to a dark-sky site, this Dobsonian delivers performance well above its price point. A robust single-speed focuser and large altitude bearings mounted to a rigid aluminum rocker box provide silky-smooth tracking even at high magnifications. The included accessory kit - with two Plossl eyepieces, a red-dot finder, collimation tool, moon filter, star map, and planisphere - means you're ready to observe the moment the telescope is assembled.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e254mm (10-inch) Primary Mirror:\u003c\/strong\u003e Gathers exceptional light for vivid views of deep-sky objects, planets, and the Moon - reaching a theoretical limiting magnitude of 14.7.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHybrid Truss Tube Design:\u003c\/strong\u003e Solid upper cage assembly protects the secondary mirror while the truss tube structure keeps the telescope lightweight and easy to break down for transport.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool-Free Assembly:\u003c\/strong\u003e Traditional truss Dobsonian setup - no tools required - gets you from the car to observing in minutes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ef\/5 Focal Ratio \/ 1,270mm Focal Length:\u003c\/strong\u003e A versatile, fast focal ratio ideal for both wide-field deep-sky views and higher-magnification planetary work.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle-Speed Focuser:\u003c\/strong\u003e Delivers smooth, precise focus control for both visual observing and astrophotography attempts.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge Altitude Bearings and Aluminum Rocker Box:\u003c\/strong\u003e Provides fluid, balanced motion across the sky with minimal vibration at any magnification - up to a theoretical 500x maximum.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e9-Point Mirror Cell:\u003c\/strong\u003e Supports the primary mirror at 9 points for consistent, accurate collimation and optimal image quality.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo Plossl Eyepieces (25mm and 10mm):\u003c\/strong\u003e Paired eyepieces cover wide-field and higher-power views right out of the box - no additional purchases needed to get started.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Accessory Kit Included:\u003c\/strong\u003e Red-dot finder, collimation tool, moon filter, star map, and planisphere provide everything a new or experienced observer needs from night one.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLimited Warranty:\u003c\/strong\u003e Backed by Explore Scientific's limited warranty - register your product within 60 days to activate full coverage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e10-inch Hybrid Truss Tube Dobsonian Telescope (primary mirror assembly, truss poles, solid upper cage)\u003c\/li\u003e\n  \u003cli\u003e25mm Plossl Eyepiece\u003c\/li\u003e\n  \u003cli\u003e10mm Plossl Eyepiece\u003c\/li\u003e\n  \u003cli\u003eRed-dot finder\u003c\/li\u003e\n  \u003cli\u003eCollimation tool\u003c\/li\u003e\n  \u003cli\u003eMoon filter\u003c\/li\u003e\n  \u003cli\u003eStar map\u003c\/li\u003e\n  \u003cli\u003ePlanisphere\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n\u003cp\u003e\n  The Explore Scientific 10-inch Hybrid Truss Tube Dobsonian is the kind of telescope that keeps calling you outside - night after night. Its massive aperture opens up a universe of targets that smaller scopes can only hint at, from the delicate spiral arms of distant galaxies to the ring of Saturn hanging in a dark sky. Explore Scientific has a long-standing reputation among amateur astronomers for producing high-performance optics at prices that don't require a research-grant budget, and this Dobsonian is a prime example of that philosophy. The hybrid truss design means you won't dread hauling it to a dark-sky site - it breaks down quickly and fits in most vehicles with room to spare. Whether you're a first-time observer stepping up to serious aperture or a seasoned stargazer looking for a reliable, no-compromise workhorse, this telescope delivers exceptional value and years of dependable use.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eView Product Specs\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eItem Number\u003c\/th\u003e\n\u003ctd\u003eDOB1045C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003ePrimary Mirror Diameter\u003c\/th\u003e\n\u003ctd\u003e254mm (25.4 cm \/ 10 inches)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd\u003e1,270mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003ef\/ratio\u003c\/th\u003e\n\u003ctd\u003ef\/5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSecondary Obstruction\u003c\/th\u003e\n\u003ctd\u003e24%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMirror Cell Support Points\u003c\/th\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTruss Pole Length\u003c\/th\u003e\n\u003ctd\u003e64 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTruss Pole Diameter\u003c\/th\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSecondary Cage Assembly Diameter (OD)\u003c\/th\u003e\n\u003ctd\u003e38 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSecondary Cage Assembly Weight\u003c\/th\u003e\n\u003ctd\u003e6.5 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSecondary Cage Assembly Height\u003c\/th\u003e\n\u003ctd\u003e17 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMirror Box \/ Rocker Box Height\u003c\/th\u003e\n\u003ctd\u003e42.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMirror Box Weight\u003c\/th\u003e\n\u003ctd\u003e~35 lbs (approximate)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eHeight to Center of Eyepiece at Zenith\u003c\/th\u003e\n\u003ctd\u003e119 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTheoretical Limiting Stellar Magnitude\u003c\/th\u003e\n\u003ctd\u003e14.7 mag\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTheoretical Maximum Magnification\u003c\/th\u003e\n\u003ctd\u003e500x\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTheoretical Rayleigh Limit\u003c\/th\u003e\n\u003ctd\u003e0.54 arc sec\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTheoretical Limiting Stellar Resolution\u003c\/th\u003e\n\u003ctd\u003e0.46 arc sec\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eAssembly Required\u003c\/th\u003e\n\u003ctd\u003eYes - tool-free truss tube assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eShipping Method\u003c\/th\u003e\n\u003ctd\u003eStandard ground shipping (free on orders $70+ within the continental U.S.)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow difficult is it to assemble this telescope?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eAssembly is tool-free and straightforward.
