It's a deep-sky observer's dream Dobsonian! The Orion XX12's jumbo 12" (305mm) Pyrex parabolic optics of 1500mm focal length (f/4.9); and a sturdy, eight-truss tube design that disassembles in about a minute into compact, easily portable components for transport to your favorite observing site! The XX12's traditional 8-pole truss tube design let's you break the tube down into portable "bite-size" pieces - no tools required! This 8-pole design provides a more rigid structural support than other designs in this category. All tube assembly knobs are captive, so you won't lose any in the dark!
The XX12 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 XX12 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. Other fine features 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 XX12 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 XX12 Truss Tube Dobsonian telescope 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.
The included XX12 Light Shroud, custom designed for the SkyQuest XX12 optical tube, is made of a stretchy nylon blend material that fits like a glove over the truss poles of the telescope, fastening with thick elastic bands on both ends. A Light Shroud is vital for optimizing visual performance in any area afflicted with light pollution or peripheral light sources like street and house lights. The water-resistant, opaque black fabric blocks stray light from entering the optical path, greatly improving image contrast. It's also breathable, which minimizes unwanted vibration of the scope in breezy conditions.
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 XX12 Truss Tube Dobsonian by Orion and hit the road to astronomical adventure.
