Orion SkyQuest XT10 Classic With Crayford Style Focuser Telescope Product Info

There are many reasons why the Orion SkyQuest XT10 Classic is 1 of our most popular Dobsonian reflector telescopes. 3 of these reasons rise above the rest simple operation, jumbo optics, and bang for your buck value. These 3 features come together elegantly in the XT10 Classic Dobsonian, making it 1 of the best telescopes to own for anyone interested in astronomy.

The SkyQuest XT10 Classic Dobsonian brings a new level of joy to simple observing as Astronomy magazine raved, thanks to its synthesis of big aperture optics and uncomplicated operation. It 39 s 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 39 s more, the XT10 Classic Dobsonian reflector telescope 39 s big mirror yields exceptionally bright views with high contrast.

The XT10 Classic 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 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 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 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 tube to the base using the CorrecTension springs. That 39 s it! You 39 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 XT10 Classic Dobsonian can give you deep space thrills without deep pocket frills. We 39 ve kept our 10 Classic Dobsonian lean and mean to keep its price low for tight budgets. But rest assured the XT10 Classic Dobsonian reflector comes fully equipped for adventure right out of the box, whether you 39 re a beginning stargazer or are graduating to a larger, more capable telescope. 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 eyepiece will wow the whole family with bright, clear, 48x power views through the XT10 Classic Dobsonian reflector.
