The Orion Build-A-Scope 12" IntelliScope Dobsonian Telescope takes big-aperture astronomy to a new level of performance and user-friendly fun. With design ingenuity and technical sophistication that make competing models yesterday's news, it will WOW even the most star-savvy enthusiast.

Its prodigious 305mm (12.0"), Pyrex parabolic primary mirror pulls down 42% more light than 10" optics and 126% more than 8" optics. What's more, the it's an IntelliScope. Which means you can just plug the IntelliScope Computerized Object Locator into the telescope's base and you're ready to find and view any of 14,000 celestial objects with the push of a button or two. Sound easy? It is.

Intelliscope Dob Chart

The Orion Build-A-Scope 12" IntelliScope Dobsonian Telescope is outfitted with an open-ventilation, aluminum mirror cell that features 9-point floating support and mounting holes for an optional cooling fan. Roller bearing construction eliminates image shift due to drawtube "rocking". Upgraded metal focusing knobs with rubber grips give you a great feel, and a thumb screw for locking the focus position and adjusting tension give you greater control.

The made-in-USA base boasts non-stick PTFE material azimuth bearings for smooth, "stiction-free" movement (not the rumblin', bumblin' roller bearings as on some other brands), and a springless, adjustable CorrecTension system for always-perfect tube balance and motion.

Although it's big, the Orion Build-A-Scope 12" IntelliScope Dobsonian Telescope is easily manageable by any fit individual. The optical tube, which uncouples from the base for transport, is 4' 10" long and 50 lbs. The base is 30" tall, 26" wide, weighs 33 lbs., and has a convenient carrying handle.

With the Build-A-Scope 12" IntelliScope 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 XT12i IntelliScope Dobsonian. You also get to select which telescope eyepiece is included from Orion's wide variety of quality oculars. Choose from low focal length, high magnification 1.25" eyepieces, or go after the bigger picture with a wide-angle 2" eyepiece to view a large swath of sky through the telescope.

If you're ready for some outrageous aperture, get the smartest big telescope to come along in years - the Orion Build-A-Scope 12" IntelliScope Dobsonian Telescope!
