The night sky has always captivated human imagination with its shimmering stars and the enigmatic beauty of distant galaxies and other celestial objects. If you are passionate about delving deeper into the universe and experiencing its wonders, one of the best ways to do this is through astrophotography.

It offers us a unique opportunity to capture the splendor of the many celestial objects from Earth.

Now, there are different types of astrophotography, including high magnification planetary imaging, wide-angle Milkway photography, and Deep Sky Object (DSO) astrophotography. Today, will be looking at DSO astrography.

I will take you through what it entails and what Telescope would be Best for DSO Astrophotography. 

So whether you are an amateur astronomer who just enjoys gazing at the night sky or you are an experienced stargazer looking to get yourself a new telescope for deep sky photography, this article has something for you. 

But before we dive deeper into the topic, we need to understand a few basics. So, let’s get right into it.

What is DSO Astrophotography?

As the name suggests, Deep Sky Object astrophotography means photographing objects that are deep in the sky, such as star clusters, galaxies, and nebulas, among others. Some of these objects are so deep in the sky that you need special equipment and telescopes to stand any chance of getting the best shots.

To master DSO astrophotography, you need to understand various aspects such as camera or telescope settings required to get long exposure images, the best way to achieve and maintain a sharp focus, and image processing, among others. We will look at some of these aspects later on in this guide.

Best Telescope for DSO Astrophotography: What You Need to Get Started

Now that you are here, you may have noticed that you need specific and potentially very overwhelming equipment to succeed in astrophotography. One of these is a telescope.

There are many options out there, but you will need a good quality telescope designed for deep sky observation if you are to succeed in DSO astrophotography.

That said, if you are a beginner, I would not recommend getting a telescope at first because there are a lot of other things that go into DSO astrophotography that you need to understand. I would, instead, suggest the following progression for you:

Learn the Night Sky

Before anything else, you first need to know your way around the night sky. A good way to do this is by using a star map. A star will help you to identify and locate various celestial objects like galaxies and stars.

A good star map will also help you to identify constellations – a group of stars that appear in a particular shape or pattern. There are 88 constellations in the sky, and knowing even a few of them and how to identify them will come in handy when trying to find other celestial objects. 

You can get high-quality monthly star maps in magazines like Star and Telescope and Astronomy. There are also online platforms, such as Stellarium, that offer good star maps.

Start with Binoculars

You may want to start small by getting a pair of good binoculars. A 7×50 pair of binocs would suffice. Getting binoculars before buying a DSO telescope is a great way to get used to stargazing, especially if you are just starting your astronomy journey.

While binoculars will not give you the same image quality as a dedicated camera or telescope will, it is a good way to get started and get used to viewing celestial objects. With a good pair, you can see star clusters, comets, and a few galaxies. You can also see the moons of Jupiter.

Consult Experienced Stargazers

When you are finally sure you want to take your stargazing hobby a notch higher, you may want to consult more experienced stargazers. A good way to do this is to enroll in a local astronomical society or club. 

The members will teach stargazing basics, such as how to get the right imaging settings and how to achieve and maintain a sharp focus. You will also get the opportunity to use different types of telescopes.

Decide the Type of Telescope You Want

When you have finally learned the ropes, you can then decide which telescope you want to buy. There are three main telescope categories: refractors, reflectors, and catadioptric telescopes. Let’s look at what each of them has to offer.

  • Refractors

Refractor telescopes are among the most popular. They are simple, with light entering the front and you viewing through the back. They use specially designed lenses to focus light from an object into an image. 

They come with two lenses. The larger one is called the objective lens and focuses light from an object inside the tube. The smaller lens is called the eyepiece lens, and it focuses light so you can view an image of the object.

With a 2-inch refractor, you can capture bright, deep sky objects, planets, and the moon, among others. 

  • Reflectors

Reflector telescopes use a single or multiple mirrors to reflect light from an object and form an image. A mirror collects light from a distant object in space and reflects it into another mirror.

The second mirror then reflects light to an eyepiece lens, which magnifies the image of the object you are viewing.

While a reflector won’t show you as much fine detail as a refractor will, it gathers a lot of light, making it easier for you to capture dimmer, deep-sky objects. 

  • Catadioptric

A catadioptric telescope is an optical scope that uses a combination of mirrors and lenses to form an image of an object. These telescopes have a higher degree of error correction than reflectors and refractors. They also come with a wider aberration-free field of view.

Get the Right Mount

After choosing your DSO astrophotography telescope, the next thing you need to do is choose a mount.

There are two types of telescope mounts: Equatorial and Alt-z mounts. An Alt-Az mount is easier to use. It comes with only two motions: side to side and up and down. An equatorial mount is designed to counteract the rotation of the Earth.

7 Best Telescope for DSO Astrophotography

Now that you know how to get started with DSO astrophotography, let’s get to the most important part of it – getting you the best Telescope for DSO Astrophotography. As I mentioned earlier, there are many of them out there, so choosing the right one may be overwhelming, especially if you are a beginner.

But do not worry, as I have got you covered. I put together a list of the best 7 telescopes for deep space photography to give the best shots of the cosmos.

I will list the key features and tell you the pros and cons of each so you can make an informed decision before buying.

How to Choose the Best Telescope for DSO Astrophotography

With so many telescopes for DSO astrophotography available today, it may be a little overwhelming when selecting the best one for your needs. Here are some of the key factors you need to consider when choosing a telescope for deep-space viewing:

Manual vs. Motorized

While motorized or computerized DSO telescopes are more expensive than manual ones, they can make the whole experience way simpler and more fun. 

Modern computerized telescopes can come with either equatorial or altazimuth mounts. Some may need to be aligned, while others use software to detect targets. With manual telescopes, you have to do all the work yourself. 

Whether you choose a computerized or manual telescope is a personal preference, but I would recommend choosing the former if you are just starting out with astronomy and don’t really know how to use the manual ones.


The size of the aperture is what determines how much light a telescope will gather from a target object. DSO astrophotography involves taking shots of some of the faintest objects in the deep sky. The aperture size is, therefore, critical. The larger the aperture, the more light the scope will gather, resulting in more detailed images.

Focal Length

Image scale and field of view are two important aspects of DSO astrophotography. The focal length of your telescope has a significant effect on these aspects. Longer focal lengths result in higher magnification, but they sometimes can make tracking celestial objects a little tricky.

A shorter focal length will provide a wider field of view, making it suitable when capturing deep-space objects or multiple objects in a single frame.


Another key aspect of DSO astrophotography is the stability of the telescope you are using. Many stargazers prefer using motorized equatorial mounts because they easily track DSOs as they move in the night sky. 

Camera Compatibility

Some DSO astrophotography telescopes come with camera compatibility. They have standard camera mounts, such as adaptors and T-threads, so you can easily attach a camera. If you would like a telescope with camera compatibility, be sure to check the specifications and features before making the purchase.

Guiding System

If you prefer long exposures, you may want to consider getting an auto-guiding system to help you correct any tracking issues and maintain correct alignment. Be sure to ask if the camera you choose accommodates an auto-guiding system.

Other factors to consider when selecting a DSO astrophotography telescope include light pollution in your area, portability, the quality of optics, the size of the telescope, and your budget, among others.

Final Thoughts

Deep sky object astrophotography can be a challenging yet very satisfying undertaking. It offers you the opportunity to observe the wonders of the universe and capture amazing shots to share with the world. 

However, you need special equipment to be able to capture objects deep in space with accuracy. One of these special equipment is a telescope. 

You need to understand the features to look for in a good DSO astrophotography telescope. This guide has covered just that. 

The 7 Best telescopes for DSO Astrophotography reviewed here are among the best, sure to give you an awe-striking astrophotography experience. Choose from among them, and I am sure you will not be disappointed.
