The SkyQuest XT10 Classic Dobsonian brings a "new level of joy to simple observing" as Astronomy magazine raved, thanks to its synthesis of big aperture optics and uncomplicated operation. It's jumbo, 10" mm diameter parabolic primary mirror gathers a ton of light from the night sky, so you can see more objects than you would with an 8" or smaller telescope.

What's more, the XT10 Classic Dobsonian reflector telescope's big mirror yields exceptionally bright views with high contrast. The XT10 Classic is refreshingly easy to use thanks to its simple, "point-and-view" Dobsonian design. Instead of a more complex tripod and mount foundation, which can be a nuisance to setup and balance, the SkyQuest XT10 reflector optical tube is supported by a sturdy wooden base. This base is what makes the XT10 Classic telescope a Dobsonian reflector by name, as the first such design was made by ingenious "sidewalk astronomer" John Dobson.

Just set the XT10 Classic Dobsonian base down where you want to observe, bring out the reflector optical tube, and securely couple the tube to the base using the CorrecTension springs.

That's it! You're ready to take the family on inspiring and educational celestial adventures exploring the planets, Moon, and a myriad of deep-sky treasures such as nebulas, star clusters, and galaxies. We've kept our 10" Classic Dobsonian lean and mean to keep its price low for tight budgets.

But rest assured; the XT10 Classic Dobsonian reflector comes fully equipped for adventure right out of the box, whether you're a beginning stargazer or are graduating to a larger, more capable telescope. The Dobsonian base supports the 10" reflector optical tube handily, and Orion CorrecTension springs help keep the tube in perfect balance while also providing secure attachment to the base.

A convenient carrying handle on the base makes transport to your favorite observing site nice and easy. The Crayford mechanism ensures all focus adjustments are smooth, accurate, and virtually free of backlash and flexure, even with heavier 2" accessories installed, so you can achieve precise focus easily.

You'll be amazed by the precise focus control as you explore the night sky. Once aligned with the telescope, just turn on the EZ Finder II and peer through the sight's small circular viewing window so you see the red dot, and move the telescope until the red dot is on the object you want to see.

Look in the telescope eyepiece, and the object will be there! The included 1. You can expand your magnification options by purchasing additional 1. Additional eyepieces sold separately. The big SkyQuest XT10 Classic Dob also includes a quick collimation cap for easy mirror alignment, and dust caps for the reflector telescope tube and focuser.

When it come to observing deep space objects, light gathering aperture is the single most important factor.

Dobsonians combine medium to large aperture Newtonian Reflector optics with a simple lazy Susan style altazimuth mount that sits directly on the ground.

This keeps the cost low without having to compromise on the size or quality of the optics. Dobsonian telescopes are the undisputed champions of deep space observing; do not be surprised to see a 25 or even 30 inch Dobsonian at your first major star party.

As stated above, the largest amateur telescopes available are Dobsonians. Large telescope are just that, large!

Three types of Dobsonian telescope are commonly available for sale. The choice between them generally comes down to what is practical based upon the aperture of the telescope. These types include the following: Solid Tube Dobsonian Telescopes: Dobsonians with solid tubes are popular in telescopes with smaller apertures, at least as far as Dobsonians go.

The optical tube assembly is a one piece affair. The most common sizes offer six, eight, and inches of aperture. Twelve inch solid tube Dobsonians are available, but most people find the optical tube assembly to be too heavy and unwieldy to be practical.

Collapsible Tube Dobsonian Telescopes: Collapsible Dobsonians feature a one-piece optical tube assembly that is capable of collapsing upon itself to reduce the overall length. The lower part of the tube with the primary mirror and upper part with the secondary mirror and focuser are permanently connected with metal poles.

With the flick of some locking levers, the entire assembly can collapse upon itself. Collapsible Dobsonians make the most sense in 12 and inch apertures, where the collapsed length of the optical tube will fit across the back seat of a car. Smaller collapsibles have little benefit, other than a reduction in storage space. Larger collapsibles are too heavy and unwieldy to be practical.

Note that the collapsible design requires the base assembly to be taller than the other types, which may be a factor to consider for both transportation and storage. Sky-Watcher Collapsible Dobsonians are an example of this type. Truss Tube Dobsonian Telescopes: Truss tube telescopes make a great deal of sense for apertures of twelve inches or more. A lower mirror box housing the primary mirror is connected to the upper cage assembly with the secondary mirror and focuser using removable truss poles.

Unlike the other two types above, this distributes both the weight and length of the fully assembled optical tube across a number of smaller and lighter components. This is what makes very large aperture telescopes practical for transportation to dark sites. Note that the base assembly of a truss tube Dobsonian is shorter, but also wider than the other types. These telescopes must be assembled in the field before they can be used. What to Expect in a Dobsonian Telescope Founded by amateur astronomers passionate about their hobby, we at Skies Unlimited have been working with hobbyists since and know what it takes and what our customers expect.

Throughout the years, we've come to work with numerous quality Dobsonian telescope manufacturers, including Meade, Orion and Sky-Watcher.

We offer a wide variety of options from each of these companies so you can find the best fit for your needs and experience. Newtonian reflector telescopes are an optical design that use a mirror to focus light into a smaller area. Most of the larger telescopes in use today utilize mirrors for economic reasons.

It is less expensive to produce a mirror than a lens, and that advantage grows with the size of the telescope. The main advantage of a Newtonian Reflector is cost per unit aperture.More than half a century later, Dobsonian telescopes are still a favorite among experienced stargazers for providing the hands-down best value-per-dollar on the telescope market.

Dobsonian telescopes are known for their large aperture and low magnification, which makes them ideal for observing faint objects in a very wide field of view. Of course, Dobsonians truly shine under dark skies in remote observing locations, but when John Dobson first invented this telescope, he used it to provide stunning views of the planets and other objects to families on the streets of urban San Francisco.

Specifically, the Dobsonian telescope is a reflecting telescope with a Newtonian optical design. This means there is a concave mirror at the end of the telescope tube and an eyepiece on the side, toward the front.

Dobsonian Telescopes

The mount is really what distinguishes the Dobsonian from a standard Newtonian telescope. Its "rocker box" mount is easy to manipulate and holds the tube like a cannon. But this new technology certainly lowers the learning curve and allows you to view many more objects in a single observing session. Plus, with the accuracy of computerized tracking, you can even use a Dobsonian for some types of astrophotography.

Thank you for subscribing!Learn More It consists of a Newtonian tube assembly riding on a simple, wooden altazimuth base. A large primary mirror at the bottom of the tube collects light and concentrates it onto a small secondary mirror, which diverts the light cone out the side of the tube and into the eyepiece.

Their affordability and simplicity of operation make Dobsonians a great first telescope for entry into the hobby of amateur astronomy, especially those in the 6" to 8" aperture range. Larger Dobs, though bulkier to transport, are highly popular among experienced observers, thanks to their tremendous light-gathering prowess and, again, their affordability compared to refractors or catadioptric telescopes.

Even relative to similar-aperture Newtonians on equatorial mounts, Dobsonians are delightfully economical. Prices valid only while supplies last and are limited to stock on hand.

They are very user-friendly, with simple optics on a simple mount that anyone can use. There are a lot of them found in stores, though, so how are you supposed to know which one is best for you? They all have different features that we will tell you about, along with any issues we may have found. It also includes a two-inch Crayford-style focuser with a 1. To top things off and make this the best inch Dobsonian telescope on the market, it has two different sizes of four-element Plossl 1.

One is 25mm, and the other is 19mm. The telescope attaches to the base with a solid rocker-mount to keep it nice and steady for the best viewing possible.

The only problem with this telescope is that it is heavy. It is compact enough to take to different places with you, but it is heavy to carry very far. This is a great telescope, but it is a more advanced scope. This telescope is attached to a stable Dobsonian base to ensure that you get the most transparent image, without any vibration.

It is also effortless to move around when tracking objects. This telescope is excellent for beginners because it is so easy to use. The only real downside to this scope is that it is very cumbersome, making it difficult to take it with you very far. There is also no comfortable grip to make carrying it more manageable.

We found the handle awkward and uncomfortable. It has two four-element Plossl 1. The scope then uses a two-inch Crayford-style focuser with a 1. It is securely attached to the base by a rocker-mount to cut down on any possible vibration.

If you are a beginner, it can be a little challenging to get started with this telescope, since there are no directions that tell you how to focus it.

It works well, but you just have to have the patience to play around with it to figure it out. Our scope also tended to drift down while viewing. You may need to readjust and tighten it periodically. It comes with two different eyepieces. One is a two-inch 28mm DeepView eyepiece, and the other is a 1. The Orion SkyQuest is easy to collimate, with an adjustable secondary mirror that uses a thumbscrew to adjust. We also found that the thumbscrew to collimate it turns easily enough, but it is challenging to get it set the way you want it.

The Zhumell Z8 Deluxe Dobsonian Reflector Telescope has an eight-inch parabolic primary mirror and two fully multi-coated eyepieces for your viewing activities. It has a collapsible tube to make it easy to transport. The Zhumell Z8 is a heavy telescope, which makes taking it places a little more difficult even with its compact size.

It is simple to get it into the position needed to view your targeted object and give you a clear view.Also called Newtonians, reflecting scopes are the best bang for the buck. They have fat tubes with a parabolic mirror at the bottom. Light from the sky enters the tube and gets reflected by this mirror back up to the top of the tube where there is a small diagonal mirror that bounces the light out the side of the tube to your eye.

A Dobsonian telescope is an alt-azimuth mounted Newtonian telescope design popularized by the amateur astronomer John Dobson starting in the s.

Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for visually observing faint deep sky objects such as nebulae.

Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for observing faint, deep-sky objects such as nebulae and galaxies. This type of observation requires a large objective diameter i. Dobsonians are intended to be what is commonly called a "light bucket" [3] operating at low magnificationand therefore the design omits features found in other amateur telescopes such as equatorial tracking.

Dobsonians are popular in the amateur telescope making community, where the design was pioneered and continues to evolve.

The term Dobsonian is currently used for a range of large-aperture Newtonian reflectors that use some of the basic Dobsonian design characteristics, regardless of the materials from which they are constructed. It is hard to classify the Dobsonian Telescope as a single invention. In the field of amateur telescope making most, if not all, of its design features had been used before.

Dobson himself identified the characteristic features of the design as lightweight objective mirrors made of porthole glassand mountings constructed from plywoodTeflon strips and other low-cost materials. Dobson's design allows a builder with minimal skill to make an extremely large telescope out of common items. Dobson optimized the design for observation of faint objects such as star clustersnebulaeand galaxies what Amateur Astronomers call deep sky object s. These dim objects require a large objective mirror able to gather a large amount of light.

Because " deep sky " observing often requires travel to dark locations away from city lights, the design benefits from being more compact, portable, and rugged than standard large Newtonian telescopes.

John Dobson's telescopes combined several innovations to meet these criteria, including:. From its inception, telescope makers have been modifying the Dobsonian design to fit their needs. The original design fit the needs and available supplies of one person—John Dobson.

Other people devised variants that fit their own needs, abilities, and access to parts. This has led to significant diversity in "Dobsonian" design. Designers started coming up with disassembleable or collapsible variants that could be brought to the site with a small SUVhatchbackor even a sedan.

This innovation allowed the amateur astronomy community access to even larger apertures.
