What's the difference between a Newtonian and Dobsonian telescope?

In your search for a telescope, the common buzzwords you are likely to come across are Newtonian and Dobsonian. What are they and what is the difference?

Newtonian Telescopes – Sir Isaac Newton invented these telescopes in 1668. They are also known as reflecting telescopes. Before reflecting telescopes, we had refracting telescopes. This design uses lenses to collect light and focus it on a single point, which often gives blurred images. Newton used mirrors in place of the lens. The mirrors reflect the light into eyepieces, giving a much clearer image.

Dobsonian Telescopes – Named after Sir John Dobson in 1960. The stand-out feature of this telescope is the altazimuth mount. This is the main structural difference between Dobsonian and Newtonian telescope.

A few other differences 

  • Dobsonian telescopes use thinner mirrors.
  • Newtonian telescopes do not travel well. They tend to lose their alignment and then require time-consuming realignment each time.
  • Paper tubes. Dobsonian tubes are made of thick industrial compressed paper, rather than aluminum or fiberglass.
  • Large apertures at affordable costs. This is one of the prime considerations of the Dobsonian design.
  • Designed with beginners in mind. The Dobsonian vision is to bring powerful telescopes to the amateur.

Dobsonian telescope is perfect for beginners

Newtonian and Dobsonian telescopes may sound similar, and, indeed, they do share common features. However, I would wholeheartedly recommend a Dobsonian as your first telescope. With a design specifically for beginners, they are easier to set-up, use, and understand. 

Here are some of the key points

  • More aperture for your money. Large apertures usually cost more. In the Dobsonian range, you will find 8” to 12” apertures (very big!) at extremely affordable prices.
  • Simple designs. As a beginner, you don’t want to struggle to set-up your telescope. Dobsonians are easy and many are point-and-view, adding to the fun experience.
  • Large light gathering capabilities and depth of sight. These scopes collect large amounts of light and focus it on a single point. This results in images that are super sharp, crisp, and clear.
  • Altazimuth mounts. Easy to use mounts that move up and down, left and right. Perfect for beginners to work with.
  • Far more portable. The best views of the night sky are usually found away from the lights and pollution of the city. Traveling with a telescope can be a challenge. Dobsonian telescopes are designed to disassemble the tube from the base. This makes it is easy to load into a vehicle and take along on an outing. 

Dobsonian telescope price timeline

The Dobsonian telescopes for beginners that we reviewed range in price from around $250 to $900. Like most high-end gadgets, you will find cheaper and more expensive models. Buying cheap is not always a good option. But, sometimes, paying a premium may not give you value for money.

Here is a quick overview of what you can expect from the different price ranges.

$100 – $300 – This cheaper range also includes a few tabletop models, which are great for traveling and easy set-up. This range usually comes with one eyepiece. They are ideal for younger and beginner stargazers. They also make great gifts.

$300 – $500 – Dobsonian scopes in this range offer large 8” lenses, which give fabulous crisp, clear views. They provide exceptional price/value ratio. Most come with two eyepieces. At this price point, you won’t get tracking.

$500 – $700 – Spending more, you will get the benefit of larger lenses up to 10”. The focal length is also longer, offering clearer and deeper views of celestial objects.

$700 – $1000 – This range offers instruments for professionals and serious amateurs. They offer 12” parabolic mirrors and a range of additional optical accessories.

$1000 Plus – At $1000+, you are entering the professional league. These scopes offer both computerized GoTo Options and manual tracking. Unique Truss-Tube designs allow disassembly for moving to observation sites around the country.

What can you see with Dobsonian?

When we first bought a telescope, the kids were super excited to see the Moon. But, we soon realized that there is a huge world of fascinating objects out there that could be easily viewed. 

Dobsonian telescopes have a wide field of view, to give the best images of the wonderful world of celestial objects. They have large lenses that gather light and give crisp images that are not distorted. The Altazimuth mount makes it easy to set-up and point the scope to focus on any object you choose. 

We soon learned about Near Space Objects. These include the Moon, the Planets, and the Sun. The special Moon Filter that comes with some models will reduce glare and bring out more contrasting surface detail. After the Moon, we focused on Saturn. Seeing the rings sends shivers down your spine! We also saw Mars’ two satellites. 

We soon got more ambitious and progressed to Deep Space Objects, known as DSOS. These include Galaxies, Nebulae, and Star Clusters. With the help of Star Guides that come with the telescopes, we were able to pinpoint constellations and learn about their fascinating ancient mythological stories. 

How to choose the right Dobsonian telescope?

Here are some key points to consider when choosing the best Dobsonian telescope. 

Aperture. For great views, choose a telescope with an aperture of 8” or more. Dobsonians offer this large range at affordable prices. With this size, you will get clear views of Moon craters and deep sky objects. 

Focal length. The longer the focal length, the better. Look for 1200 to 1500mm as a starting point. 

Mount. Most Dobsonian telescopes come with Altazimuth mounts. These are lightweight, easy to set-up, and use. They move up and down, left and right. Telescopes with tabletop mounts are great for traveling.

Portability. If you plan on taking your stargazing out of the city, you will certainly get the benefit of clearer, less polluted skies. Your scope needs to be lightweight and compact. Scopes that can be disassembled are best. If they don’t come with a carry bag, invest in a sturdy padded bag that protects your instrument while in transit. 

Ease of set-up. Spending hours aligning your telescope is not something you want to do. Point-and-view models are simple and get you stargazing in no time. 

Extra Accessories. Extra accessories add value to your viewing experience. Different size lenses give different magnifications. Moon filters enhance the view. Finderscopes make it easy to locate your objects.
