Imagine standing beneath a dark sky dotted with stars, your gaze carrying you far beyond the edge of our galaxy. Now, how can we bring the sky within reachable distance? The astronomer’s most important tool is a telescope. But are telescopes hard to use?
First, there are many different kinds of telescopes, for example, Dobsonian and Cassegrain. Some are easier to use than others. The major telescope brands offer easy-to-use models for the beginner. Some of the best telescopes on the market require some experience.
Navigating the sky can be a daunting endeavour, with a telescope’s components each serving their own unique purpose. You’re not just buying a large instrument with lenses or mirrors; you’re investing in a dream that promises glimpses of distant planets, stars, and galaxies.
But to easily use a telescope, you need to understand how it works. You may be asking, “How does a telescope capture the distant objects of space? What are the different parts of a telescope, and what do they do?” I’ll answer these questions and more in this guide.
Let’s discover how to use a telescope without difficulty together, shall we? Welcome to your first step towards becoming a master of the telescope!
The Anatomy of a Telescope: Understanding Its Various Parts
At first glance, a telescope seems to be very complex and difficult to use. To a beginner, this can be very offputting, but I’d like to help you by explaining what I have learned in my years since first trying to use a telescope. I’ve got a lot to tell you!
Are telescopes hard to use?
First, it’s worth noting that, according to this interesting post on the forum Cloudy Nights, 60% of beginners find using a telescope challenging during their first attempt.1
I know I did! And challenging isn’t the word. Let’s demystify the whole process of using a telescope by first understanding what the different parts of a telescope are and what they do. This can help us.
Telescopes are made up of several key components: the aperture, the eyepiece, the mount, and the finder scope.2 We’ll look at each one of these here.
The Aperture
The aperture is the diameter of the telescope’s main lens or mirror3, and it’s the most important aspect of a telescope. Larger apertures allow more light to be collected, providing a brighter and more detailed image.
We’ll examine why some telescopes have mirrors and others have lenses and how this will affect how you use your telescope. It comes down to the type of telescope you have. If you have a reflector, as I do, it will have mirrors to reflect the light to the eye. If you have a refractor telescope, you’ll have a lens through which the light travels and focuses onto your eyepiece.
The Eyepiece
Now let’s think about the eyepiece.
The eyepiece is the part of the telescope that you look through.4 It magnifies the image that the telescope’s primary lens or mirror has focused. Eyepieces come in different magnifications, and choosing the right one depends on what you’re trying to observe.
The Finder Scope
The finder scope does what it says on the tin; it finds your objects. I have a small finder that gives a laser light point that appears in my view, indicating where my telescope is pointing. I move the telescope until my object comes into view in the eyepiece, and the laser light point should be centred over the star or object I am looking at. This will then tell me the exact spot I am aiming for.
OK, now we have learned what the different parts of a telescope are and what they are used for. Next, I’ve got some tips that I learned with much practice that will help you understand how to use your telescope.

Tips for First-Time Telescope Users
Are telescopes hard to use? They can be challenging for beginners.5 They require patience and practice to master, particularly when it comes to locating and tracking objects.
It’s like anything else, though; at first, it is unfamiliar and confusing, but with practice and knowledge, you can learn how to use a telescope quite easily. Just be prepared for some initial frustration and a steep learning curve, depending on the kind of equipment you have.
Here is another fact I found that illustrates how difficult it can be for a beginner in astronomy to use a telescope:
Nearly 50% of beginners give up using a telescope due to its complexity within the first year.6
A major point I want to make here is that you should not give up with your telescope because there is a mysterious and beautiful universe up there to discover! It’s not beyond you, and I know because I mastered how to use a telescope with little help other than various Youtube videos and some helpful websites and forums that pointed me in the right direction.
Here are some tips for using a telescope:
- Learn about your equipment and what it can do. The first step is to read the manual and do some research online.
- Understand what you want to do with your telescope and know the limits your equipment has. What is its aperture? What are you likely to be able to see with your telescope?
- Choosing the right telescope is important. What is the best telescope for viewing galaxies? or this page I’ve written about telescopes for seeing planets.
- Figure out how to aim your telescope first and read about your astronomical target. Decide what you want to look for.
- The first couple of times you use the telescope, aim at a large target, such as the moon. Don’t look for something faint or hard to find. Small steps are better than no steps at all.
- Learn how to focus and things like how to change the eyepiece.
- Try observing first. Astrophotography is much harder and can be done after you first learn how to use a telescope.
- If your telescope has no form of tracking, you’ll have to manually adjust it, and you’ll soon notice how quickly objects like the moon or stars move across the sky.
- If your telescope has a GOTO computerised mount, you’ll need to learn how to use it and spend a few nights trying to figure this out. Practice aligning the scope on different stars and see if you can get it to find a target for you. Here is a list of some of the brightest stars to align your telescope to.
- Persevere! Do not give up, even though your first night may not be what you planned. Be happy to have seen something special in the night sky, and let this inspire you to learn more about how to use your telescope.

How a Telescope Works
Telescopes work by collecting light from a distant object and focusing it to create an image.7 The larger the telescope’s aperture, the more light it can collect and the finer detail it can resolve.
For a beginner, this might sound pretty straightforward, right? However, in practice, using a telescope isn’t exactly as simple as pointing it towards the sky, and voila, you’re an astronomer! There’s a fair bit of complexity you need to overcome before you can get full enjoyment from your telescope.
There are two types of telescopes refractors and reflectors. While refractor telescopes use lenses to gather light, reflector telescopes employ mirrors for the same purpose. How light is collected and focused in these types plays a significant role in what you see when you peer through the eyepiece.
The eyepiece, for example, is where you look into the telescope. It magnifies the image that the telescope has collected and focused. Depending on what you’re viewing, you might need to use different eyepieces. It’s a bit like changing lenses on a camera; you wouldn’t use a wide-angle lens to take a close-up shot of a bird, would you?
The mount is another critical part of your telescope. It supports the telescope and allows you to move it around to point at different parts of the sky. There are two main types of mounts: azimuth (altitude) and equatorial. Knowing which to use can improve your stargazing experience significantly.
In astrophotography, the mount is critical as it locates and tracks objects while you photograph them.
As with any skill, practice makes perfect. The more time you spend learning about your telescope and how it works, the better you’ll become at using it. And remember, don’t be disheartened if you’re finding it tricky at first. Keep at it, and the cosmos will soon be within your reach!

Using a Telescope to Photograph the Cosmos
Let’s talk about astrophotography now.
Are telescopes hard to use for astrophotography? The answer is yes.
I found it very difficult at first, so be prepared to solve several problems depending on what equipment you have and how much you know about astronomy.
Here are some of the challenges you’ll face when using a telescope for astrophotography:
- How to focus on objects you cannot see, such as stars or other objects.
- How to find deep-sky objects that you cannot see but want to photograph.
- How to track the movement of the stars accurately so you don’t get star trails in your photos.
- How to attach a camera to your telescope.
- How to set up and align your telescope for good-quality astrophotography.
- How to take long exposures of many seconds or even minutes.
- How to adjust your telescope and make sure it is ready for astrophotography.
These are just some of the difficulties of using a telescope for astrophotography. The journey and experience of astrophotography bring a whole new reason to use a telescope because it opens up the universe in all its glory! I love it.
Language of the Stars: A Beginner’s Guide to Telescope Terminology
The first layer of complexity that awaits a new astronomer is the language that we use to describe the equipment and techniques used. You need to understand what the terms mean, and this may involve learning some actual science.
Descriptions of astronomy and space, parts of a telescope, different kinds of telescopes and optical systems, filters, cameras, the physics of light, magnification, and photography are all parts of this language you’ll need to learn and understand.
Throughout this website, I explain these terms as best I can using my skills as a teacher and my experience over the last so many years as an amateur astrophotgrapher. Please check out the links to more information in this post for more information about anything I mention here.
Oh, and if you need to ask any questions or need more information, don’t hesitate to contact me, and I’ll gladly try to help you.
Enhancing Your View: Telescope Maintenance and Care
There are only a few things to learn about how to maintain your telescope so you can get the most out of it. This includes:
- Collimation can be quite challenging for beginners, but it is essential to have crisp, clear views of distant galaxies and nebulae.
- Regular cleaning and correct storage of your telescope can significantly enhance your viewing sessions and extend the life of your device.
- Correct use of the telescope parts and taking care of your equipment are very important if you want to enjoy astronomy. Learn how to use everything properly and be careful, as your telescope is a scientific instrument and delicate.
Telescope Setup Instructions
Let’s discover how to setup a telescope.
How to align Your Telescope
There are a number of different ways to align your telescope. I have used three methods, and generally, the method you use will change as you progress in astronomy, whether you use your telescope for viewing or astrophotography.
The three methods I’ve used to align my telescope, from easiest to most advanced, are:
- Manually pointing the telescope at an object.
- Aligning my telescope on two or more stars. This requires some kind of Goto system in your telescope mount. If you have an alt-az mount, you do not need to Polar Align, but if you have an equatorial mount, you do. Find out how to Polar align here.
- Connecting your telescope to a laptop or computer and using plate-solving to align and locate objects. This is for the more advanced telescope user, but once you do this, it saves time and is quite easy. I always use this now. Discover how to use plate-solving here.
Conclusion and for more information about telescopes
It takes time and some skill to master how to use a telescope to get the most out of it. As you progress in astronomy or astrophotography, you’ll want more advanced equipment. It’s well worth spending a bit more to acquire good quality, but there are cheaper alternatives for the amateur telescope user.
Enjoy your telescope and your astronomy!
