The XT12 IntelliScope 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. And now the
XT12 comes with a 2" Crayford-style focuser for improved performance.
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 XT12 is an IntelliScope. Which means you can just plug the optional IntelliScope Computerized Object
Locator into the scope'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.
This scope is outfitted with an open-ventilation, aluminum mirror cell that features 9-point floating support and mounting holes
for an optional cooling fan. The 2" Crayford-style focuser accepts both 2" and 1.25" eyepieces. The Crayford-style focuser is
smoother and more accurate than a rack-and-pinion focuser. 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 focuser includes an adapter for 1.25" eyepieces.
You also get a 9x50 dovetail finder scope and our exclusive navigation knob for easy slewing. The made-in-USA base boasts Teflon
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 XT12 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.
If you're ready for some outrageous aperture, get the smartest big scope to come along in years â€" the XT12 IntelliScope!
Mirror, optical tube, and base packaged separately; some assembly required. One-year limited warranty.
