The Sky-Watcher 10" DOB: The Sweet-Spot for Aperture and Value!


This is a big, friendly horse of a telescope you can ride off into the sunset with, and then thrill to well resolved celestial views when twilight fades. The SW 10" DOB is an very satisfying telescope to own, an instrument that will provide a lifetime of continuing exploration of the heavens. This telescope will hit the sweet-spot for many amateurs, providing all the capability and value you are seeking in a large aperture telescope. 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 a large aperture telescope that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-transportability.


Viewing with the SW 10"—Size Does Matter


In viewing deep-space, aperture matters—big time! With this telescope you have tremendous light gathering power. Prominent deep-space objects seen well in an 8" SW DOB, such as diffuse emission nebulae in the summer sky like the Lagoon (M8), Trifid (M20), and Swan (M17); the stunning globular star clusters M13 and M92 in Constellation Hercules; the awesome winter sky's Great Orion Nebula (M42) in Constellation Orion, and our enormous local galaxy group companion the Andromeda Galaxy (M31) in Constellation Andromeda, to name a very few, will appear more spectacular, brilliant, and wider in extension in a SW 10" DOB.


Many challenging objects for an 8" aperture now come into their own with the SW 10" DOB: the planetary nebula the Crab (M1), a supernova remnant, requires a 10" aperture to truly begin to appreciate the several subtle, gaseous filamentary structures. M33 the spiral galaxy in Constellation Triangulum exhibits significantly more open arm structure. The Rosette Nebula in Monoceros begins to show the discernable pattern of a blooming rose. M51, the fascinating spiral Whirlpool Galaxy, displays remarkable greater structural detail in a 10" aperture vs. 8" diameter size telescope.


There is no question the incremental resolving power of a 10-inch aperture is visually impressive when compared to an 8-inch. Therefore, it is no wonder then that the 10" aperture is overtaking the 8" as the serious amateur astronomer's aperture of choice in a Dobsonian telescope. Sky-Watcher's compact, collapsible optical tube design makes the decision to step up in aperture to a 10" even easier.


Sky-Watcher 10" DOB – a Class Act!


The Sky-Watcher 10" DOB 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.
On each parabolic primary mirror, and elliptical diagonal mirror aluminum is vacuum deposited to the front glass surface and then over coated with hard quartz (SiO4). Additional layers of Titanium Dioxide (TiO2) and (SiO4) are then applied


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.


Sky-Watcher Dobsonians Epitomize Ease-of-Use


Observing with a Dobsonian has been described akin to shooting ducks in a gallery because it is so easy to find your target. Just swing your SW DOB to the quadrant of sky to be searched, and scan the vicinity. An 8x50mm Right Angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping. The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments. Multi-coated, 4-element Pl?ssl eyepieces (25mm and 10mm) provide a spacious 52? Apparent Field of View.


To ensure mechanical ease-of-use, SW 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 SW 10" DOB, so constant mechanical adjustment of the telescope's orientation isn't needed to keep objects in the field of view.

    Comments about Sky Watcher Sky-Watcher 10 Inch Dobsonian Telescope:

    I received this scope a year ago for my birthday. I have to admit....it took a bit of practice to learn how to find things, but once I did,it was worth the effort. The scope is very well made and the mechanics are smooth and stable. As far as a mass production scope, I would compare the Skywatcher to anything else out there. I have added a red dot finder in addition to the finder it comes with and plan to add a shroud as well. Collimation is easy and a given with this kind of telescope. It only takes a minute to collimate and you are off and running. I would love to have the mirror tested to see just how good it really is.The eyepieces that come with it are starters at best. I have since purchased a 13mm Ethos and a 27mm Panoptic from Telescopes.com and I have to say....you will never look back. The views through this scope are off the hook. It's kind of ironic that I spent twice as much on eyepieces than I did on the scope, but that is the nature of this hobby. The views are really only as good as your eyepieces. At one point, I was thinking of upgrading to a high-dollar dob, but I like the mechanics of this scope so much, I may just upgrade the mirrors at some point. I just don't like the look of some of the expensive dobs out there. I am currently trying to work out a counter-weight system to compensate for the heavy eyepieces which is a bit of a challenge as there is little room on the back of primary. I may go with a SCT weight system and modify to fit. All in all, a great purchase. I have since purchased an 8 inch dob, 125mm etx, and a well known high end 80mm refractor, and the Skywatcher 10 inch is still my absolute favorite as the observatory I built to house it will attest.I wish they would come out with a 16 inch.....aperature fever... and a collapsing base would be nice too. Well done Skywatcher and Thank You Telescopes.com

      I am really enjoying this telescope. You will want to replace the stock plossl eyepieces pronto and get yourself a shroud. Seems to hold collimation well.

      This is a great Scope. The first one I recieved had a chipped secondary mirror but Telescopes.com took care of me with no hassles. [...]Love the scope. I recommend a light shroud and an upgrade to the inclided eye pieces.

      Comments about Sky Watcher Sky-Watcher 10 Inch Dobsonian Telescope:

      This is a great deep sky object telescope. I bought it about three days ago and could not be more pleased. The image of the moon is sharp and crisp and huge! Whether you use the Plossl 26mm or the Plossl 10mm included eyepieces the image fills in the field of the eyepiece was nicely! But I would definitely recommend viewing the moon with a filter. The views of the peaks and valleys and slight variations in the shadows really highlights the power and quality of this scope. I have also checked out some unbelievable views of star clusters. I use to own 6-inch reflecter and there is no comparison. It is like a completely different world. The only drawback of the Dobsonian is that you must be prepared to collimate the mirrors before every viewing. So a collimation tool is a must. Also I would recommend purchasing a O2 cool 10" 12-volt fan from a famous local department store in your area. It fits perfectly into the space just below the mirror. The fan runs both on AC adapter and batteries. The Dobsonian mount accesses any view with absolute ease. And the tension knob works reasonably well. My only main complaint is about the finder scope. It is very accurate. But because you are viewing at a very comfortable right angle at a fairly high power it is difficult to get an exact fix on where you are looking. That one minor inconvenience set aside I cannot more highly recommend this scope! This difficulty with the finder is not a flaw in design. That is the nature of the beast. That is why I decided to still give this scope an overall rating of 5.0.
