Description

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 a 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 Plossl eyepieces (25mm and 10mm) provide a spacious 52 degrees 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:

    Overall a nice, easy to use, capable telescope that is good for beginners. I use it with my 8 year old son, and there are no worries about it being too complex or delicate for him to use. We observe in the front yard, and set up/collimation takes about 15 minutes tops. The collapsible truss system is well designed, as is the entire OTA, including the primary mirror adjusting screws. I think the optics are good, but the jury is still out as skies have not cooperated since I bought a "good" lens. The focuser has only coarse adjustment and I wish it also had a fine adjuster like some other scopes in this class. It is not gear driven, but some sort of friction roller - not sure how that will hold up over time. Sometimes I spend more time making sure it is in optimum focus than I would like. The mount is made of particle board, again like others in this class. It works well overall, but altitudinal and azimuthal motion is not as smooth as the advertising suggests. On my unit, one of the three (small!) teflon pads on which the base plate rides fell off out of the box. They are only stapled into the particle board, which is CHEAP. The clutch system of the altitudinal adjuster also can be tricky to operate - hard to get it just right, not too tight, not too lose. It usually takes some effort to get your target centered in the eyepiece. Plastic bushings line the particle board holes of the altitudinal adjusters, and one of mine has fallen out and is lost already (2 weeks). Finally, one of the large screws supplied to assemble the Dobsonian mount was defective out of the box (bent, messed up threads), which seems par for the course in our globalized, made in [*]economy. I can put another screw in easily enough.So, after 2 weeks of ownership I am happy with the performance and think this scope will serve our family well for years to come. I think the primary mirror/OTA is very good quality, which is the most important thing. The mount works OK, but I'd encourage the manufacturers to continue to improve upon it. I can live with the minor deficiencies listed here and am happy overall with our purchase.

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

      As other reviews have noted, this is a very convenient scope to use due to the collapsing truss design. I can have the scope set up in just a couple of minutes. It is easy to collimate with a laser collimator and I recommend you purchase one. It has an excellent finderscope and a decent focuser. I do not like the 2" adapter set up however, and found it inconvenient to use The mirror seems to produce excellent bright images and I am quite happy with the optics. I do not believe you need a shroud for this scope. It does not have a cooling fan and I made one using a simple computer fan with a 9 volt battery and taped in onto the back of the mirror cell. However, I have not found that this scope takes very long to cool down even if the fan is not used. The mechanics are a bit rougher. Using the hand clutch produces a lot of popping noise since you are compressing the base into the altitude bearings. It is really quite annoying, especially during star parties. I also found the altitude movements quite stiff. I have tried a number of fixes and so far putting a bit of graphite on the plastic bearings seems to work. I have also heard of other people who put a bit of Vaseline on them with good results. 2" eyepieces pretty much require a counterweight. I picked up a welding magnet for a few dollars at [...] which does the job.

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

      A very good telescope that finds a neutral ground between a full sonotube dob and a truss dob by eliminating the annoying bits of both. The collapsible truss rods are pretty ingenious - you'll be able to move it in one piece by yourself and have the whole thing set up in under a minute.
      Optics are good . . . probably great, but I don't know enough to act like I can make a good call here. Stars are precise points, no blue glow around planets and brighter objects, good deep sky contrast, so I'm guessing pretty good.
      Construction quality is pretty great, too. The OTA, viewfinder, and focuser are all metal and feel substantial and durable. The alt/az base is pretty standard stuff - particleboard with Teflon bearings. One really cool feature is the hand-controlled "clutch" system that can be used to compensate for large eyepieces or tons of kit on the secondary mirror cell. Many dobs require weights to compensate, but this one does it at the twist of a handle.

      Only con I can think of is that I wish it came with a mirror cell fan - the cell supports are tapped to hold an 80mm fan and the mirror is large enough that cool-down time is an issue.
      And, this is a non-issue but raised an eyebrow - the focuser requires an adapter for both 1.25" and 2" eyepieces. Uhhhh . . .
