About the Orion SkyQuest XT10 Classic Dobsonian Telescope...
There are many reasons why the Orion SkyQuest XT10 Classic Dobsonian Telescope is one of our most popular Dobsonian reflector telescopes. Three of these reasons rise above the rest: simple operation, jumbo optics, and bang-for-your-buck value. These three features come together elegantly in the Orion Telescope XT10 Classic Dobsonian, making it one of the best telescopes to own for anyone interested in astronomy.
The Orion SkyQuest XT10 Classic Dobsonian Telescope brings a "new level of joy to simple observing" as Astronomy magazine raved, thanks to its synthesis of big aperture Orion Telescope optics and uncomplicated operation. Its jumbo, 10" (254mm) diameter parabolic primary mirror gathers a ton of light from the night sky, so you can see more objects than you would with an 8" or smaller telescope. What'''s more, the XT10 Classic Dobsonian reflector Orion Telescope''s big mirror yields exceptionally bright views with high contrast.
The Orion SkyQuest XT10 Classic Dobsonian Telescope is refreshingly easy to use thanks to its simple, "point-and-view" Dobsonian design. Instead of a more complex tripod and mount foundation, which can be a nuisance to setup and balance, the Orion Telescope SkyQuest XT10 reflector optical tube is supported by a sturdy wooden base. This base is what makes the SkyQuest XT10 telescope a Dobsonian reflector by name, as the first such design was made by ingenious "sidewalk astronomer" John Dobson.
The base supports the Orion Telescope 10" reflector optical tube handily, and Orion CorrecTension springs help keep the tube in perfect balance while also providing secure attachment to the base. Non-stick PTFE and UHMW bearings provide buttery smooth motion in both altitude (up/down) and azimuth (left/right) axes, as you move the Orion SkyQuest XT10 Classic Dobsonian Telescope from object to object. A convenient carrying handle on the base makes transport to your favorite observing site nice and easy. Just set the base down where you want to observe, bring out the reflector optical tube, and securely couple the Orion Telescope tube to the base using the CorrecTension springs. That'''s it! You'''re ready to take the family on inspiring and educational celestial adventures exploring the planets, Moon, and a myriad of deep-sky treasures such as nebulas, star clusters, and galaxies.
The Orion SkyQuest XT10 Classic Dobsonian Telescope can give you deep-space thrills without deep-pocket frills. We'''ve kept our 10" Classic Dobsonian lean and mean to keep its price low for tight budgets. But rest assured; the Orion Telescope XT10 Classic Dobsonian reflector comes fully equipped for adventure right out of the box, whether you'''re a beginning stargazer or are graduating to a larger, more capable telescope.
The Orion SkyQuest XT10 Classic Dobsonian Telescope includes a 2" Crayford focuser, EZ Finder II reflex sight aiming device, 25mm Sirius Plossl telescope eyepiece (1.25"), and quick-collimation cap are all standard equipment. The 2" Crayford focuser features a step-down adapter so you can use both 1.25" and 2" telescope eyepieces with the XT10 Dobsonian. The included EZ Finder II makes it easy to aim the telescope accurately, and the 25mm Plossl telescope eyepiece will wow the whole family with bright, clear, 48x power views through the Orion Telescope XT10 Classic Dobsonian reflector.
Enjoy fantastic views with the Orion SkyQuest XT10 Classic Dobsonian Telescope - and fantastic savings too!
