The Best Telescope For Deep Space Observation

The best telescope for deep space is the one that works great for what you’re trying to accomplish with it. There are numerous aspects to consider when purchasing a telescope. There is no single best telescope for all. If a telescope is too large, you will find it difficult to use, and if it is too small, you won’t be able to see distant objects. 

The most notable thing about a telescope is its size. Your budget and how far you intend to look when viewing also factor into the equation, but the most important thing is how big a telescope you can handle and still enjoy using.

What is a Deep Space Telescope?

Source: NASA

As humans, we are unique in the universe. The only planet to have evolved as we did and the only one to look up at the stars. We have a strong desire to explore the unknown, which has allowed us to travel into space and even land on the moon.

Even though we have come a long way since we first looked up, there is still much more to discover about our galaxy and beyond. That’s where a deep space telescope comes in. It allows us to look further and deeper into space than ever before, learning more about our universe and potentially finding another planet like Earth.

What Does A Deep Space Telescope Do?

A deep space telescope does exactly what it sounds like; it allows you to see further, deeper into space. They’re usually bigger than other telescopes because they need powerful lenses or mirrors that collect as much light possible from distant objects such as stars, planets, galaxies, etc.

The larger the light-collecting area of your telescope, the brighter the image will be when viewed through it, which helps tremendously with viewing objects outside our solar system!

The Orion 10013 GoScope 80 Tabletop telescope is the best tabletop telescope for deep space viewing. Its 80 mm aperture gives you a sharp, clear view of galaxies, nebula, and distant planets. It’s easy to set up and simple to use, so you can get focused on the stars at hand instead of getting tangled up in a complicated telescope.

The Orion 10013 GoScope is a refractor telescope, which means it uses lenses to gather light and create an image for you to look at. Refractor telescopes with large lenses are great for viewing objects in deep space because they allow the lightest possible into the scope. 

Additional factors that make this model great:

Light from these more distant objects usually comes in at an angle distorted by the atmosphere or other factors, so having your scope’s lens be as large as possible is key for getting a clear view. The Orion 10013 GoScope 80 Tabletop has an 80 mm lens diameter, about 3 inches wider than many tabletop scopes.

It’s also significantly more powerful than most tabletop scopes. The Orion 10013 GoScope 80 Tabletop has a magnification range of 160x power, much higher than the typical 50x power you’ll find in similar tabletop telescopes. 

This allows you to see things like craters on the moon, rings around Saturn, or even faint nebulae. It also comes with all of its own accessories: tripod mounting hardware, eyepieces, a red LED flashlight, plus instructions on how to use everything properly.

You Should Take A Few Things Into Consideration Before Buying

Telescopes are an important tool for stargazing, and there are several models available on the market. However, not all telescopes are made equal, so you need to consider a few things before you buy.

If you’re looking for the best telescope to see deep space objects but don’t know where to start, then this guide will help. When evaluating your investment, there are a few factors to keep in mind. Let’s take a closer look at a couple of them:

Source: AstroBackyard


The larger the telescope that you buy, the more you’ll be able to see. When looking for telescopes, remember that the best telescopes for deep space viewing are going to be larger than 15 inches. This is because they need to have a large objective lens, which means that they need to have a lot of glass in order to focus on an object and make it appear as if it were right next to you.


The price of a telescope is going to vary depending on what features it comes with and how many of them it has. There are some telescopes that come with just one feature or another, while others come with all of them. If you want the best telescope for deep space viewing then you’re going to have to pay more than $500 dollars for it, which will get you a good one with a lot of features.

Telescope Type

There are two main types of telescopes: refractors and reflectors. A refractor uses mirrors instead of lenses and this leads to a clearer view, but there are limitations when it comes to size. Reflectors are ideal for observing deep space because they can be manufactured much wider than refractors. The only downside is that these telescopes need more regular maintenance as the mirrors will gather more dust than lenses.

Field of View (FOV)

Field of view (FOV) and Field of View Angle (FVA) are two terms that refer to the same thing. This angle determines how much detail your eyes can see through the lens. You will notice that some telescopes have a higher field of view than others. 

However, there are many different types of telescopes out there that come with different fields of view so make sure to check out your options before purchasing one for yourself.


A telescope’s mount is one of its most crucial components. It needs to be sturdy enough to hold your larger telescope, otherwise, it’ll wobble around every time you breathe. It also needs to be easy to use because otherwise, you’ll spend more time setting up than actually viewing.

Source: spaceplace


Not all telescopes have the same magnification capabilities. If you plan on viewing very small objects like planets or stars, then a smaller aperture size may be adequate for your needs. However, for larger objects such as galaxies and nebulae, consider purchasing one with a larger aperture so that it can magnify distant objects well enough for them to be seen clearly by the naked eye. Also note that the higher the magnification number is, the harder it will be to see details about an object as well as its surroundings. 


If you plan on traveling with your telescope, it is important to consider how easy it is to move around and store away. Many telescopes can be transported in one piece and set up in minutes, while others need to be broken down into smaller parts and reassembled after each move. You also need to consider the weight of the equipment when picking out a telescope for deep space objects. The heavier the device is, the more difficult it will be to transport and move around.


If you’re going to be using the telescope every night, then you want something that’s easy to use and maintain. You should also consider if you’ll be able to see deep space objects through them without having any problems. Some telescopes are better suited for viewing certain types of celestial bodies than others. For example, some telescopes are better at viewing comets than planets or stars.

Eyepieces and Accessories

Many telescopes come with one or two eyepieces. These enable you to zoom in on objects in the sky giving different magnifications depending on which one you use. Some telescopes also come with other accessories such as a camera adapter so that you can take photos through the telescope or a Barlow lens which increases the magnification power of the eyepiece being used.

Bottom Lines

The above was just a quick summary of the different types of telescopes, as well as a recommendation for the best telescope for deep space observation. The different types of telescopes above will all be terrific choices if you are looking to get started in astronomy.  

I hope that you found this article on different types of telescopes to be helpful and educational, and I also hope it inspires you to start observing the night sky in your own backyard.
