As you run through the checklist of attributes you've heard are important in a good beginner's telescope, you realize that the Orion Build-A-Scope 6" Classic Dobsonian Telescope meets all the criteria - in spades. Astronomy magazine called the standard configuration on which this model is based "an excellent entry-level Dobsonian telescope for an adult."

Classic Dob Chart

It's a telescope that opens up limitless observing possibilities. With its big 150mm diameter parabolic primary mirror the Orion Build-A-Scope 6" Classic Dobsonian Telescope collects nearly 80% more light than a 4.5" reflector, rendering brighter images and greater detail in deep-sky nebulas and star clusters. And the 1200mm focal length gives the telescope ample power to zoom in on subtle planetary and lunar features.

The 45"-long enameled-steel optical tube glides with silky smoothness on the Dobsonian wood base. You just point the telescope and view! Orion-engineered CorrecTension springs keep the tube balanced to perfection and allow the whole unit to be carried together by the handle on the base.

With the Build-A-Scope 6" Classic Dobsonian from Orion, you decide which finder scope, eyepiece, and other accessories come 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 XT6 Classic Dobsonian. You also get to select what 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 the sky through the telescope.
