Dobsonian telescope is a reflecting telescope mounted on a simple but effective horizon-type mount, which is invented and popularized by amateur astronomer John Dobsonian in the 1960s. It is placed in a box or bracket and can be tilted up and down. The box itself is mounted on a rotatable platform so you can turn the Dobsonian telescope horizontally.

Dobsonian telescopes work by reflecting the light traversing inside their OTA (optical tube assembly) from a curved primary mirror onto a flat secondary mirror which subsequently directs the light to the focuser. The exceptional feature of Dobsonian telescope is the altazimuth mount. It is an easy-to-use mount that can move left, right, up, and down. Depth of sight and large light-gathering capabilities are two other key characteristics of this kind of telescope. So, Dobsonian telescopes collect huge amounts of light and then focus it on a single point.

Basic Dobsonian telescope is a portable and affordably priced telescope. These telescopes utilize thinner mirrors and the tubes are usually manufactured of thick industrial compressed paper instead of fiberglass or aluminum. It can’t track stars, but its simple design means you can usually save money on a larger telescope. Its design is intended for beginners, so they are easy to set up and use. Enjoy planetary observation at the best with the choice of the best Dobsonian telescope for beginners from the following selection.

How To Pick The Best Dobsonian Telescope for Beginners?

When deciding to get the best Dobsonian telescope for beginners, the knowledge of the following factors simplifies your buying decision.

1. Manual vs. Motorized

Dobsonian telescopes are usually available in two configurations – a manual mount and a motorized mount.

The manual mount is an easy ‘point and shoot’ system that allows you to manually control the movements of the telescope using your hands. Firstly, you need to find the object on your own via the tiny finder scope that is mounted on the main telescope. Next, you need to look for it in the eyepiece. Note that it needs the knowledge of the sky. However, don’t worry because it is very easy to study from the star maps. 

If you are fine spending some extra money then you can go for a motorized mount implemented with the GoTo system. In these types of telescopes, you can still move the telescope manually but you will also benefit from the comfort of the GoTo system. Note that the mount is implemented with an electric motor and you can control the telescope using the handset. You simply need to press a few buttons and the telescope will slew to the object you chose. Consequently, it saves you time finding the object.

2. Aperture

The aperture decides how vivid the images are and whether you could see finer details. To obtain great views, make sure to pick a Dobsonian telescope with an aperture of 8 inches or more. With an aperture of 8 inches or more, you obtain clear views of deep-sky objects and Moon craters.

3. Stability of the base

The majority of the Dobsonian telescopes are uniquely designed to offer a firm base that offers great stability to the entire telescope unit. It is recommended to check this feature before purchasing. The decent stability not just enhances your work experience but also helps you to hold the telescope in the position you want.  Moreover, decent stability lets you move the telescope in the direction of the object you wish to observe.

The excellent stability of the base facilitates easy point-and-view navigation, smooth motion, and easy tracking. Also, it conveys a vibration-free image even when viewed at high power.

4. Other features

You can take into account some additional features to make the most of the purchase. For example, you can look for a Dobsonian telescope that is equipped with superior quality parabolic mirrors that guarantee superior light transmission. Also, it is better to choose the one that comes with efficient magnifying and optical accessories like various filters and eyepieces, computerized object locators, cooling fans, etc.

Components of A Dobsonian Telescope

Primary Mirror

The primary mirror refers to the first mirror for incident light in a reflective telescope, it is generally the largest mirror in the telescope. The primary mirror collects and focuses light from distant objects and reflects it back to the secondary mirror.

Secondary Mirror

The secondary mirror is the second mirror that the starlight encounters after being reflected by the primary mirror to the reflecting telescope. Its diameter is generally smaller than that of the primary mirror. The secondary mirror turns the light 90 degrees and reflects it to the focuser on the other side of the barrel.

Barrel Assembly

The barrel assembly includes the secondary mirror and the primary mirror, with the focuser and star finder attached to the exterior. Some users of Dobsonian telescopes use a truss construction rather than a closed barrel.

Focuser and eyepiece

As with the reflecting telescope design, the eyepiece and focuser are located at the top of the barrel and protrude from the side of the telescope.

Altazimuth mount

Dobsonian telescopes use a altazimuth mount, where one axis can be tilted up and down and the other axis can be rotated horizontally. The altazimuth mount is a way of supporting a telescope that allows the telescope to move freely in parallel and vertical horizontal directions. The general popular telescope adopts the horizontal bracket, which is simple and light in structure and also cheap in price.

Finderscope

The finderscope is a small, low-power telescope attached to a large telescope to help observers find the location of celestial objects. It is a miniature telescope with a wide field of view that allows you to focus on your target.

The finderscope generally adopts double separation or double glue objective lens, with a diameter of 5 to 10 cm, and a reticle for aiming at the focal plane. The field of view is generally about 3°, and eyepieces with a large field of view are commonly used, their magnification is about 10 to 20 times.

FAQs When Picking The Best Dobsonian Telescope for Beginners

1. How does a Dobsonian telescope work?

The optics of Dobsonian telescopes function identically to Newtonian telescopes. Usually, they have a parabolic primary mirror or a concave spherical mirror at the rear. The corresponding mirror gathers and focuses the incoming light over a flat secondary mirror. Subsequently, the secondary mirror reflects the image into the eyepiece. 

2. What is the difference between a Newtonian telescope and a Dobsonian telescope? 

Generally, Dobsonian telescopes use thinner mirrors and provide bigger apertures than Newtonian models. On the other hand, Newtonian telescopes are usually heftier than Dobsonian telescopes. Note that the key difference is the Dobsonian mount. Special Altazimuth mounts are found in a lot of Dobsonian telescopes. 

3. What magnification a Dobsonian telescope should have if you want to see planets?

If you want to see planets like Saturn and Jupiter then magnification of approx. 30x is a minimum requirement. If you want to see planets like Mars then magnification of approx. 100x is a minimum requirement.

4. Can you capture pictures with the best Dobsonian Telescope for Beginners?

Yes, you can capture pictures using a Dobsonian telescope from a reliable brand. Make sure that the telescope you purchase allows connecting a Digicam or a DSLR camera.

Final Thoughts

The best Dobsonian telescope for beginners eliminates the hassles of setting up the telescope. Their simple design, ease of setup, and tons of useful features make them very beneficial for beginners. The output from these telescopes depicts crisp, clear, and super-sharp. They are great for planetary observation, boast large apertures, and don’t suffer from image distortion.
