Maybe the idea of a big-aperture telescope appeals to you, but the portability issue has kept you on the fence. Well you can hop off it now because we've got the perfect solution - the "space-saving" Orion SkyQuest XX12i IntelliScopeŽ Truss Tube Dobsonian. It's a deep-sky observer's dream telescope, offering jumbo 12" (305mm) Pyrex parabolic optics of 1500mm focal length (f/4.9); a stylish, reduced-weight base outfitted with computerized IntelliScope object locating technology; and a sturdy, eight-truss tube design that disassembles in about a minute into compact, easily portable components. And at its price, the XX12i ranks as the #1 killer telescope deal of the year!

Truss Tube Dob Chart

Finally, a deluxe, large-aperture Dobsonian that fits comfortably into a compact car for transport to your favorite observing site! Credit the XX12i's traditional truss tube design, which utilizes eight aluminum trusses (four captive pairs) that attach and detach quickly with oversized hand knobs - no tools required! This design provides a more rigid structural support than other designs in this category. And all assembly knobs are captive, so you won't lose any in the dark! When removed, the trusses in each captive pair align in parallel, which saves space when transporting and storing them. Disassembly of the 56"-long optical tube yields two sections, the largest measuring just 26" in length.

The XX12i improves on the already stellar features and performance of our standard XT12 IntelliScope Dobsonian. The focuser is a dual-speed (11:1) 2" Crayford with 1.25" adapter, metal focus knobs, and adjustable drawtube tension to ensure excellent, non-slip motion for any size of eyepiece used. We outfitted the XX12i with larger, 8" altitude bearings for smoother tube motion. The side-reinforced base sports stylish cutouts that minimize weight without sacrificing stability. EbonyStar laminate glides on non-stick PTFE material bearings to give the azimuth motion the feel of silk. Fine features carried over from the XT12 include adjustable altitude tension, an open 9-point flotation primary mirror cell, and a "navigation knob" for easy slewing.

Although the primary mirror cell is extremely well ventilated, the Orion SkyQuest XX12i Intelliscope Truss Dobsonian comes with a Cooling Accelerator Fan, which attaches to the back of the cell and facilitates faster equilibration of the mirror to ambient temperature. The secondary mirror has a 70mm minor axis and is held in a four-vane spider with very thin (0.7mm thick) vanes to minimize diffraction effects.

The acclaimed IntelliScope Computerized Object Locator comes standard on the XX12i, allowing manual slewing to any of 14,000 celestial objects in just seconds, using its illuminated pushbutton keypad. It lets you spend your time viewing celestial objects instead of hunting for them. What's more, with the XX12i's Truss Dobsonian 305mm of light-grabbing aperture, your favorite "faint fuzzies" won't look nearly so faint or fuzzy! The deep-sky views will simply dazzle you.

The XX12i Truss comes fully loaded with great accessories, including a 9x50 finder scope, aluminum telescope eyepiece rack, two telescope eyepieces: a low-power 35mm (43x) DeepView 2" and a high-power 10mm (150x) Sirius Plossl 1.25", dust caps for the top and bottom optical tube sections, and a "collimating cap" to insure optical alignment of the mirrors. A convenient carrying handle is provided for the base.

It's the big Dobsonian you've dreamed of owning, and now you can take it with you wherever dark skies beckon! Get the practical and amazingly affordable Orion SkyQuest XX12i IntelliScope Truss Tube Dobsonian by Orion and hit the road to astronomical adventure.

Media Buzz

Sky & Telescope - July 2009
"I was struck by the attention to little details, all based on time-tested Dobsonian principles, that demonstrated that this scope was designed by someone who understood how it would be used in the field."

"If the SkyQuest XX12i IntelliScope were a car, it would be the model that dealers keep in the showroom to impress prospective buyers."

"The XX12i comes with the most effective altitude friction adjustment I've seen on a commercial Dob... The motions of the SkyQuest are among the best I've experienced..."

"If good optics in an easy-to-aim, well-built scope were the end of the story, the 12-inch SkyQuest would be a winner. But there's much more."

"I had fun using the computerized locator. I really got a kick out of choosing objects at random just to see what would greet me in the eyepiece. It was fun - and isn't that what telescopes are all about?"

"Of the three commercial 12-inch Dobsonians I've used in recent months, the XX12i is the one I enjoyed the most."

"I think the SkyQuest XX12i IntelliScope Truss Tube Dobsonian is the ideal next scope for any observer who has learned his or her chops on an 8-inch or smaller instrument and is ready to move up to something bigger."

Astronomy Magazine - August 2009
"...I swung the [XX12i] toward the Orion Nebula (M42), which lies in the Hunter's sword. The view through the 35mm eyepiece was that evening's "wow" moment. Faint tendrils of nebulosity filled the field. It was striking."

"Returning to the Trapezium with a 5mm eyepiece (300x), I noted that the image remained sharp and clear. Even boosting to a ridiculous magnification of 700x didn't compromise the view, a testament to the XX12i's optical excellence."

"I came away impressed with Orion's XX12i. In it, intelligent design and high-quality components come together to create one of the finest instruments of its size sold today."

"If you're a visual deep-sky observer like me and are looking for a telescope that will enthrall you for years, the XX12i should be on your short list of candidates."

WARNING! When using a truss tube Dobsonian telescope for solar observing, always use a Light Shroud and a properly sized solar filter. When you install the Light Shroud make certain there are no gaps between the Shroud and the telescope where direct sunlight can reach the telescope mirror. When a truss tube telescope (equipped with a solar filter but no Light Shroud) is pointing near (not at) the Sun, direct sunlight can hit the mirror and focus on the solar filter or other portions of the telescope. This can lead to eye injury or damage to the telescope. Using a Light Shroud protects your telescope from peripheral sunlight.

Before using any telescope for solar observing, make sure to install all dustcaps or other protective covers on all optical components such as finder scopes to keep sunlight from passing through them. Glancing through an uncovered optical system, even for an instant, can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.
