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’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’s more, the XT10 Classic Dobsonian reflector telescope’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 XT10 Classic telescope a Dobsonian reflector by name, as the first such design was made by ingenious “sidewalk astronomer” John Dobson. Just set the XT10 Classic Dobsonian 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’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 XT10 Classic Dobsonian 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 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.
Orion CorrecTension springs make setup easy and keep the telescope balanced.
The Dobsonian 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
Dial-in celestial details with the smooth and accurate 2″ Crayford focuser.
The SkyQuest XT10 Classic Dobsonian features a 2″ Crayford focuser with a removable step-down adapter so you can use both 1.25″ and 2″ telescope eyepieces. The Crayford mechanism ensures all focus adjustments are smooth, accurate, and virtually free of backlash and flexure, even with heavier 2″ accessories installed, so you can achieve precise focus easily. You’ll be amazed by the precise focus control as you explore the night sky.
The included Orion EZ Finder II red-dot sight makes it easy to aim the telescope.
Following a simple alignment procedure, you can use the EZ Finder II sight to accurately aim the SkyQuest XT10 Classic Dobsonian telescope at objects in the sky like the Moon and bright planets. Once aligned with the telescope, just turn on the EZ Finder II and peer through the sight’s small circular viewing window so you see the red dot, and move the telescope until the red dot is on the object you want to see. Look in the telescope eyepiece, and the object will be there!
Explore the night sky with the included 25mm Sirius Plossl Eyepiece.
The included 1.25″ Orion 25mm Sirius Plossl eyepiece provides a 48-power view when used with the SkyQuest XT10 Classic Dobsonian. Offering a wide 52° apparent field of view, the 25mm Sirius Plossl eyepiece yields extremely sharp, high-contrast images that will impress night after night. You can expand your magnification options by purchasing additional 1.25″ or larger 2″ wide-angle eyepieces of different focal lengths. (Additional eyepieces sold separately.)
