Classic Dob Chart

This Orion Build-A-Scope 10" Classic Dobsonian gives you the deep-space thrills without the deep-pocket frills. We’ve kept it lean and mean to keep its prices low for tight budgets. But rest assured, it comes fully equipped for adventure, whether you’re a beginning stargazer or are graduating to a more capable telescope. It features an expertly figured parabolic mirror housed in an enameled steel optical tube. The tube rides on a stable Dobsonian base that allows easy point-and-view navigation and has a convenient carrying handle.

With the Build-A-Scope 10" Classic Dobsonian from Orion, you decide which finder scope, focuser, and eyepiece comes with the telescope. You can choose between magnified achromatic finder scopes, red-dot reflex sights, or more deluxe right-angle correct-image or illuminated crosshair finder scope models to be included with the SkyQuest XT10 Classic Dobsonian. Next, select which focuser you want to be included with the telescope, choosing between smooth-adjusting Crayford designs with or without dual-speed fine focus control. You also get to select which telescope eyepiece is included from Orion’s wide selection of quality oculars. Choose from low focal length, high magnification eyepieces, or go after the bigger picture with a wide-angle eyepiece to view a large swath of sky through the telescope.

Setup takes only a minute, leaving the rest of the evening to marvel at the planets, the Moon, and a myriad of deep-sky treasures. Enjoy the fantastic views with the Orion Build-A-Scope 10" Classic Dobsonian Telescope — and savings!
