Sky-Watcher 12" Collapsible Dobsonian Reflector Telescope

The Sky-Watcher 12" DOB is a big gun. If you are shooting for well resolved, elusive 12th-magnitude fuzzies, you now have the power. In fact, a very significant wow-factor extends down to viewing the stuff people usually concentrate on with 8" and 10" telescopes. Except they say, "WOW!", when they view through this super aperture amateur 12" SW telescope. You can not only be a hero to yourself, but a mystical guru to other backyard astronomers, scout groups, friends, and neighbors. Astronomy is a great hobby to share, and a SW 12" DOB makes you potentially the hit of any star party. Well, so much for ego satisfaction—the point is—the SW 12" DOB is a serious telescope that will be purchased by a serious amateur who wants serious deep-sky penetrating resolution. Be advised this Light Chariot is one sweet astronomical ride!

Viewing with the 12" Sky-Watcher Dobsonian Telescope - Deep-Space Hero!

Everything in deep-space appears brighter, and wider in extension with the SW 12" DOB. Many of the more challenging to resolve objects in smaller diameter telescopes now reveal their essential structure. Objects just within the threshold of a 10" aperture now appear more prominent and may be worth dwelling upon for extended periods. Comet hunters will delight in the fainter magnitudes that are possible to discern in the SkyWatcher 12" Dobsonian telescope. Here at last is a telescope within the threshold to tackle elusive deep-space gems like the Horsehead Nebula in Constellation Orion. Located in Constellation Perseus, M76, is a very faint nebula of 11th magnitude. The SW 12" will capture this baby like you want to see it. M97, a planetary nebula in Ursa Major is very faint, but as a serious amateur you will want to see it. No worries, the Sky Watcher 12" DOB will fulfill your quest. M61, a spiral galaxy in Constellation Virgo, will reveal spiral arms as you would hope to see them, but you will need a SW 12" telescope to resolve them well. The list goes on, and you will delight in planning your own journey of exploration.

The incremental resolving power of the SkyWatcher 12" aperture is beyond just being impressive, it's within amateur astronomy's super aperture threshold where the lucky observer is able to resolve well, many, many objects that smaller telescopes just don't have the horsepower to detail satisfactorily because they can't pull in enough light. Again, Sky-Watcher's compact, collapsible optical tube design makes this super aperture 12" DOB a far more practical decision to purchase.

Sky-Watcher Dobsonians Epitomize Ease-of-Use...

Observing with a Dobsonian has been described akin to shooting ducks in a barrel because it is so easy to find your target. Just swing your Sky-Watcher Dobsonian to the quadrant of sky to be searched, and scan the vicinity. The included 8 x 50mm right angle optical viewfinder provides both magnification and light-gathering to help narrow your search. The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments, and the multi-coated, 4-element Plossl eyepieces (25mm and 10mm) provide a spacious 52º Apparent Field of View.

To ensure mechanical ease-of-use, Sky-Watcher USA uses a high-performance Teflon bearing system in both axes, combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction, assuring smooth vertical and horizontal manual movement without free-play from small bumps or gusts of wind. This also eliminates the need to have a balanced optical tube as in an equatorial mount. Sky-Watcher's Teflon bearing system is preferable to the use of ball-bearings. Ball-bearings make unintended movement of the optical tube more difficult to control. Fortunately, at low power, deep-space objects leisurely drift through the field of the Sky-Watcher 12" Dob, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view.

Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece, low-hassle OTA design is mechanically simple and results in large aperture telescopes that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-transportability.

The Sky-Watcher Dobsonian Telescope Uses Quality Components Throughout...

The Sky-Watcher 10" Dobsonian utilizes quality components throughout. Pride of workmanship manifests itself in high quality standards of optical and mechanical fabrication. The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast, and properly corrected optics show minimum alterations to the optical wave-front.

Aluminum is vacuum-deposited to the front glass surface on each primary mirror and elliptical diagonal mirror and then over-coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied. Dust covers help keep your telescope clean when not in use.

The mechanical and structural components of the OTA exhibit rigid construction and outstanding stability. The mount construction is sturdy and rigid. Mount design, while simple, facilitates smooth motions about both axes. Quality accessories enhance the observer's viewing experience.

Oversize Shipping Charges Statement...

Large Dobsonian telescope boxes are considered oversized by UPS, which causes the shipping costs to sky-rocket. Because of these high shipping charges, OPT has no other choice (unless we want to lose money on the sale) but to pass part of the charges on to the customer. Therefore, please note that the price shown above does not include a $50 oversize box fee. The amount will be added to your order before the telescope ships. If you pick the telescope up at OPT, by the way, you will not have to pay this fee. Thank you for your understanding.

Nice scope, but awkward to move alone

Review by Michael / (Posted on 9/24/2009)
I've used this 3 times (total use in heavy dew - no dewing on the secondary. Focuser robust, smooth & solid. Knocked off a half point for the 2 adapter - why a 2 adapter for a 2 focuser? Motions in both axis's smooth with little to no vibration. Don't even use the altitude brake. No tools needed to collimate the primary. 2mm allen wrench needed for the secondary. Collimation is close from setup to setup. Less than 5 minutes spent and you're good to go. I would rate the mirror from good to very good with pin point images. I'm highly satisfied with the mirror quality. Contrast is very good without the shroud but I've got one ordered anyhow. I'm nervouse about something falling in on the mirror through the open struts. Heavy plastic, fitted covers for the mirror section & the upper cage. Dislikes: 2 focuser adapter. Likes: this telescope is good to go from the box and is a pleasure to use without mods. Remember though that this is a 12 telescope and is going to be heavy to move. Some of the other, major telescope makers should take a lesson from Skywatcher on how to build a dobsonian telescope right the first time! One more thing, for what this thing is selling for now ($795, it's a steal!
