Our largest Dobsonian reflector yet is an ideal combination of three key telescope features: large aperture, convenient portability, and precise GoTo object location. Thanks to its 16" aperture parabolic primary mirror, the Orion SkyQuest XX16g GoTo Truss Tube Dobsonian will astound you with spectacular views of the night sky. Its Orion-designed collapsible Dobsonian base and 8-pole truss optical tube makes transportation of this hefty telescope easy since the entire telescope can be disassembled without tools into small, manageable component pieces that can fit in virtually any standard size car. You'll be able to enjoy the XX16g's large-aperture optics thanks to the accurate, motorized GoTo system which will automatically locate and track any of over 42,000 celestial curiosities within its computerized database of night sky objects.
The powerful, high-tech, and downright BIG SkyQuest XX16g 16" GoTo Truss Tube Dobsonian takes deep-sky observing to new space-penetrating depths. It is the latest and largest in our line of fully automatic GoTo truss tube Dobsonians. For serious amateur astronomers seeking big-aperture exhilaration, state-of-the-art GoTo electronics, and a clever Dobsonian design that is transportable in almost any size vehicle -- the XX16g is an ideal "lifetime" telescope!
Wait, you're thinking, it fits in almost any size vehicle? Yes, you can take this big telescope with you, because both the Dobsonian base and optical tube of the XX16g were engineered by Orion to quickly disassemble - without tools - into easily manageable components, the heaviest of which (base groundplate assembly) weighs 61.4 lbs.
Both the 16"-diameter (406 mm), lightweight parabolic primary mirror and 91mm minor-axis secondary mirror of the SkyQuest XX16g are made of low-expansion glass and feature enhanced 94% reflectivity aluminum coatings for optimal observing performance. The XX16g delivers a giant 77% jump in light grasp compared to a 12" Dobsonian reflector, and even a sizeable 30% gain over a 14" aperture telescope! Those elusive celestial objects you once considered "faint fuzzies" won't be nearly so faint or so fuzzy through the SkyQuest XX16g GoTo Truss Tube Dobsonian! You'll enjoy views that simply cannot be seen in smaller telescopes.
The lightweight primary mirror cools more efficiently than standard flat-back parabolic mirrors, thanks to its thin, curved-back design. The primary mirror is held in place by an open-ventilation mirror cell which also helps the mirror to acclimate quickly. This special mirror cell features three large knurled knobs for easy collimation adjustments, and can accommodate an optional 12V Three Fan Cooling System (sold separately) for even faster temperature equilibration.
While the XX16g is easy to disassemble for convenient portability, once it's assembled it is a very solid telescope. The rigid 8-pole truss tube provides great structural rigidity of the optical tube and virtually eliminates flexure that can affect 6- and 3-pole designs. The XX16g GoTo Dobsonian base utilizes thick, 1" composite wood panels for extra-strong support, and features perpendicular struts that brace the side panels when assembled for rock-solid performance. All base boards are laminated with water-resistant melamine.
The XX16g's SynScan GoTo system includes a database of over 42,000 celestial objects. Dual optical encoders and servo motors in each axis pinpoint any object you select with the backlit hand controller and track its motion. The closed-loop electronics let you slew the telescope by hand if desired, while still maintaining the GoTo alignment. Heavy-duty clutch knobs on both axes can be adjusted to the desired level of resistance.
Now all SkyQuest XTg and XXg GoTo Dobsonian telescopes - including this one - come Wi-Fi enabled, which means they can be controlled wirelessly from your smartphone or tablet instead of with the cabled SynScan hand controller! Just download the FREE SynScan Pro app to your iOS or Android device to enjoy wireless GoTo control! The SynScan Pro app is not a planetarium program, but rather provides similar intuitive menus and functions as the SynScan hand controller. Once you go wireless, you may never go back to "cable" again!
If you were to point the XX16g Dobsonian optical tube straight up, the telescope eyepiece would be positioned 72-3/8" (6.03') above the ground. Of course, during most observing sessions the eyepiece will be considerably lower than this maximum height, but no matter where you point the XX16g at night, you're sure to be astonished by the bright, sharply detailed views this amazing telescope provides.
The SkyQuest XX16g comes equipped with a 2" dual-speed Crayford focuser with 1.25" adapter, and includes a 28mm 2" DeepView eyepiece and a 12.5 mm illuminated reticle eyepiece for precise GoTo system alignment. Other accessories include an EZ Finder II reflex sight, eyepiece rack, GoTo hand controller bracket, 12V DC power cable, and RS-232 cable for firmware updates. A 12V field battery or AC-to-DC adapter (sold separately) is required for motorized operation.
An optional Light Shroud for the optical tube is also available and highly recommended (Light Shroud sold separately). Keep your XX16g optical tube safe and clean during transport or storage with the recommended optional Case Set (sold separately).
It's a BIG telescope you can take anywhere! Get the Orion SkyQuest XX16g and enjoy jaw-dropping views of the night sky in a big yet pleasantly portable GoTo Dobsonian telescope.

BBC Sky at Night magazine, June 2013 "Due to their sheer size, large-aperture commercial Dobsonians often present practical difficulties ...Orion's XX16g overcomes many of these difficulties with an innovative design that enables it to be broken down into smaller and lighter parts."
"One of the best features of this scope is the GoTo system, which allows the scope to automatically seek out any object you select from the handset's database. The motors continue to smoothly track the object once centered."
"The XX16g's innovative design features enhance the appeal of owning a large Dobsonian and we expect to see several at this year's UK star parties."
WARNING! When using a truss tube Dobsonian telescope for solar observing, always use a Light Shroud and a properly sized solar filter. When you install the Light Shroud make certain there are no gaps between the Shroud and the telescope where direct sunlight can reach the telescope mirror. When a truss tube telescope (equipped with a solar filter but no Light Shroud) is pointing near (not at) the Sun, direct sunlight can hit the mirror and focus on the solar filter or other portions of the telescope. This can lead to eye injury or damage to the telescope. Using a Light Shroud protects your telescope from peripheral sunlight.
Before using any telescope for solar observing, make sure to install all dustcaps or other protective covers on all optical components such as finder scopes to keep sunlight from passing through them. Glancing through an uncovered optical system, even for an instant, can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.

Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.
Advanced Level - These products provide the best performance but may require more skill to master and appreciate. Optical instruments with this rating have exceptionally fine optics and mechanics. Some are easy to use but might be on the large or heavy side. Some are intended for specialized uses. These products will appeal to the more technically inclined. Referring to the manual is highly recommended.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
