Orion SkyQuest XX12g GoTo Truss Tube Dobsonian Telescope
... transportable 12" (305mm) f/4,9 Telescope with positioning and tracking

Orion Skyquest xx12 Goto Dobson

An elegant combination of three astronomical attributes: powerful optical performance, convenient collapsible portability, and modern motorized GoTo and tracking technology

Big 12" aperture reflector optics bring in a huge amount of light from the night sky for great views of nebulas, galaxies, star clusters and solar system targets like the Moon and planets

Orion-designed collapsible GoTo Dobsonian base AND 8-pole truss optical tube both break down into easily manageable components for transport in virtually any car
Closed-loop electronics forgive accidental bumps, nudges, and even manual repositioning without losing alignment of the GoTo system and heavy-duty clutches allow independent adjustment of motion to desired level of resistance in both axes.

Includes a 35mm DeepView 2" eyepiece, 12.5mm illuminated Plossl 1.25" eyepiece, eyepiece rack, EZ Finder II reflex sight, 2" extension tube, reflector collimation cap, 12V DC power cable, Cooling fan, Starry Night software, and more!

More informations:

Orions most advanced 12" Dobsonian reflector telescope is geared up for extensive exploration of the night sky. With fully motorized GoTo and tracking drives providing automated pointing to any of the over 42,000 celestial objects in the hand controller's database, the Orion SkyQuest XX12g GoTo Truss Tube Dobsonian is truly a telescope that will keep you up at night - in a good way.

Orion designed the XX12g's optical tube and base with portability in mind. The truss tube can be divided into a small front tube section including the secondary mirror and focuser, rear tube section housing the primary mirror cell, and the four truss-pole pairs. We've increased the portability of the XX12g compared to its XX12i IntelliScope-equipped counterpart by making the base collapsible for easy no-tools-required disassembly into four separate, smaller pieces for easier transport. The separated component pieces of the XX12g tube and base can be stored without taking up an excessive amount of space in your home, and can be transported in virtually any standard-sized car to your favorite dark-sky observing site.

The XX12g telescope optical tube employs a rigid 8-pole truss design that virtually eliminates flexure observed in 6- and 3-pole collapsible tube designs. Stability of the assembled XX12g Dobsonian base is enhanced by its 1" thick composite wood base panels, which are laminated with water-resistant black melamine. GoTo and tracking motors are pre-installed on the base panels, making assembly nice and easy. Once the tube and base are assembled, the optical tube attaches to the base with a dovetail trunnion and locks securely in place with a single captive hand knob.

The XX12g GoTo system automatically slews the telescope to any of the over 42,000 celestial objects you choose from the hand controller's intuitive menus, once a simple alignment process is completed. Altitude and azimuth motors automatically track the motion of the target object so it stays put in the eyepiece field of view for extended visual study. For anyone who has spent an evening manually tracking objects with a Dobsonian this is a profound upgrade, and trust us, it was worth the wait. Forgiving of bumps and nudges, the XX12g features closed-loop electronics allowing manual repositioning, or slewing, of the telescope tube without losing alignment of the GoTo system. Redesigned heavy-duty clutches allow motion in both axes to be adjusted independently to desired level of resistance.

With 12" (305mm) of light gobbling aperture and a fast f/4.9 focal ratio, the XX12g is capable of providing clear, crisp and very bright views of the night sky in a 2" or 1.25" eyepiece installed in its 2" dual-speed Crayford focuser with 1.25" adapter. The 12" diffraction-limited parabolic primary mirror is crafted from low thermal expansion glass for speedy ambient temperature acclimation and optimal visual performance. The included cooling accelerator fan helps hasten temperature acclimation of the primary mirror (requires 8 D-cell batteries, or other 12V power source, not included). The primary mirror features enhanced reflectivity aluminum coatings which provide 94% reflectivity and a protective quartz overcoat, so you get the most out of each and every photon collected.

The XX12g is outfitted with a thorough set of included accessories. A 35mm DeepView 2" eyepiece provides wide 56° views and a 12.5mm illuminated Plossl 1.25" eyepiece helps optimize GoTo system alignment. A collimation cap, removable eyepiece rack, 12V DC power cable and RS-232 cable are also included. A 12V power supply (sold separately) is required for use of the GoTo system and motors.
