Quick Overview

Orion XX12g GoTo Truss Tube Dobsonian Telescope



  • 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 28mm 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!

Details

The Orion  XX12g GoTo Truss Tube Dobsonian Telescopeis Orion's 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.


Truss Tube Dob Chart


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 28mm 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.


A specially designed Light Shroud is available (sold separately) for the Orion XX12g optical tube. A Light Shroud significantly enhances the viewing experience in a Truss Tube Dobsonian by blocking distracting   peripheral light from entering the light path, optimizing contrast and brightness.


A custom Orion Padded Case Set (sold separately) is available for the XX12g Dobsonian optical tube. Each set of cases includes a padded case   for the top tube section including a secondary mirror cover, a padded case for the bottom tube section, and a roll-up case to safely hold the   truss-pole assemblies. An Orion Padded Case Set is the best way to preserve and protect your investment for years to come.


With the Orion SkyQuest XX12g GoTo Truss Tube Dobsonian telescope, you're amply equipped for big-aperture visual adventures, wherever you  may roam.
