SkyQuest XX12i IntelliScope Truss Tube Dobsonian
If the idea of a big-aperture telescope appeals to you, but the portability issue has kept you on the fence, you can hop off it now. We?ve got the perfect solution - the SkyQuest XX12i IntelliScope Truss Tube Dob. It?s a deep-sky observer?s dream scope, offering jumbo 12" Pyrex optics (f/4.9); a stylish, reduced-weight base outfitted with IntelliScope object location technology; and a sturdy truss tube design that disassembles in about a minute into compact, easily portable components.

Finally, a deluxe, large-aperture Dobsonian that fits comfortably in a compact car for transport to your favorite observing site! The eight trusses (four captive pairs) provide more-rigid support than other designs in this category. We?ve also outfitted the XX12i base with nothing but the best materials: EbonyStar laminate and UHMW azimuth bearing surfaces provide silky smooth azimuth motion. Equipped with dual-speed (11:1) 2" Crayford focuser, large 8" altitude bearings, full set of great accessories, a computerized database of 14,000 celestial objects - and a price just north of a grand! - the XX12i is one killer telescope deal.

It?s the big Dob you?ve dreamed of owning, and now you can take it with you wherever dark skies beckon! Get the practical, amazingly affordable SkyQuest XX12i and hit the road to astronomical adventure.

SkyQuest XX12i Truss Tube Dobsonian Shroud
Black shrouds are usually so funereal - but not when you?re talking truss tube Dobs! For the best performance from any truss Dob, a shroud is a must. This one, custom designed for the SkyQuest XX12i, is made of a stretchy nylon blend material that fits like a glove over the truss poles of the XX12i, fastening with thick elastic bands on both ends.

The water-resistant, opaque black fabric blocks stray light from entering the optical path, thus improving image contrast. It?s also breathable, which minimizes unwanted vibration of the scope in breezy conditions. Use of the shroud will lessen the accumulation of dust and dirt on the mirrors during use, and will help prevent dew from forming on them. Made in the U.S.A.

SkyQuest XX12i Truss Tube Dobsonian Case Set
The beauty of a big truss tube Dob is that it can be disassembled into conveniently sized components for easy transport. And transporting the SkyQuest XX12i will be much easier, and the components much better protected, with this set of cases designed just for the XX12i.

The set includes three cases plus a secondary mirror cover. Each case is made of durable, waterproof, 600-denier polyester/nylon material with a urethane coating and a 100% nylon lining, and double stitched for extra strength. There are separate padded cases for the upper and lower optical tube sections as well as a case for the truss poles. The poles slip into separate compartments to prevent direct contact among them.

The truss case attaches to the lower optical tube case with a hook-and-loop fastener so the two can be carried together as one. The lower tube case also has a zippered pocket to hold accessories. All the cases have carrying handles. Lastly, the soft nylon secondary mirror "sock" is included to keep the mirror free of dust when the scope is idle. Keep your SkyQuest XX12i Truss Tube Dob looking like new and get it to your observing site more easily and securely with this set of custom cases. Made in the U.S.A.

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 XX12 IntelliScope were a car, it would be the model that dealers keep in the showroom to impress prospective buyers."

"The XX12 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 XX12 is the one I enjoyed the most."

"I think the SkyQuest XX12 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 [XX12] 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 XX12?s optical excellence."

"I came away impressed with Orion?s XX12. 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 XX12 should be on your short list of candidates."
