How to Choose the Right Telescope: Advice on what to look for when choosing a telescope
Are you looking for a telescope, but you don't know what to look for? Don't worry, choosing the perfect telescope doesn't have to be complicated. In this blog post we will take you through the essential aspects to consider when choosing a telescope. From understanding magnification to assessing lens quality and ease of use, at Vultus we help you find a telescope that's perfect for your needs. Let's discover together how to choose the telescope that gives you the best view of the stars.
Stargazing for Beginners: Your Guide to Choosing Your First Telescope
The Importance of Magnification Power in Telescopes
Understanding magnification power is crucial for stargazing beginners. This power, expressed as a number followed by 'x' (for example 40x), indicates how many times closer an object appears than to the naked eye. Although it may be tempting to choose a telescope with a very high magnification, this is not always the best option. For example, a telescope with a magnification of 150x can bring the moon very close, but it can also make the image darker and blurrier, especially if the telescope has a small lens or mirror. So it's important to find a telescope with a magnification power that provides a clear and sharp image, which often means that a moderate magnification of around 50x to 100x is ideal for most beginners.For those just starting out with stargazing and looking for a suitable telescope, the Telescope 80/500 375x for Beginners is an excellent telescope to start with.
Telescope Mounts: The Basics Explained
The mounting of a telescope is just as important as the telescope itself. There are mainly two types: azimuthal and equatorial montages. Azimuthal mounts are simpler and more suitable for beginners, while equatorial mounts offer more precision for advanced stargazing activities. Choosing the right mount depends on your observation goals and experience level.
The Importance of Resolution in a Telescope
The Role of Optical Quality in Telescopes
The optical quality of a telescope largely determines the quality of the observations. This includes aspects such as the purity and quality of the lenses and mirrors used. High-quality lenses and mirrors minimize aberrations such as chromatic aberration, where colors do not coincide correctly, resulting in brighter, sharper images. For example, a telescope with a well-polished, large mirror will collect more light and provide a clearer image than a telescope with a smaller, less refined mirror. These telescopes are often also more expensive, although nowadays there are very budget-friendly telescopes that also have high-quality mirrors. This is difficult to assess yourself and the Resolution and Clarity: Key Factors for Nocturnal Observations
Resolution and clarity are essential for observing night sky objects. Resolution determines how much detail you can see, while brightness determines how well you can see faint objects. A telescope with a large aperture (diameter of the main lens or mirror) will collect more light, leading to a brighter image and better resolution. This is especially important for observing distant or faint objects such as distant galaxies or nebulae.
Lens Quality and More: How Do You Judge a Good Telescope?
The Influence of Lens Quality on Image Quality
The lens is extremely important for the quality of the telescope. A high-quality lens captures more light and provides a brighter, sharper image. The diameter of the lens also plays a role in this. A larger diameter means a wider lens and therefore more light. It is important that the lens can handle this. If the lens is of poor quality, the lens may not be able to handle it, causing blurred vision. This is essential for both amateur stargazers and experienced astronomers.
Reflective vs Refractory: What's the Difference?
Reflecting and refracting telescopes are two fundamentally different types of optical telescopes, each using light in a unique way to form images of distant objects.
-
Refractive Telescopes:
- Operation: Refractive telescopes, also known as dioptric telescopes, use lenses to bend (or refract) light. The most essential part is the objective lens, which is located on the front of the telescope. This lens collects light from an object and combines it into a focus point.
- Advantages: They are generally simpler and more robust due to their closed tube design, which means they require less maintenance. They also provide sharper and brighter images in smaller sizes, making them ideal for terrestrial observation and for observing planets and the moon.
- Disadvantages: Refractive telescopes can suffer from chromatic aberration, where light of different colors is not focused exactly on the same point, which can lead to colorful fringes around objects. Larger refracting telescopes can also be very heavy and expensive.

-
Reflecting Telescopes:
- Operation: Reflecting telescopes, or catoptric telescopes, use a combination of curved mirrors to reflect light. The primary element is a concave primary mirror at the back of the telescope. This mirror reflects the light and focuses it on a secondary mirror, which then directs the image to the eyepiece.
- Advantages: Reflective telescopes are better suited for observing faint and distant objects in deep space, such as galaxies and nebulae. They do not suffer from chromatic aberration and can achieve larger diameters at a lower cost and weight than refracting telescopes.
- Disadvantages: They require more frequent alignment or collimation and are more prone to dust and dirt due to their open tube design. This may require more regular maintenance.

Both types of telescopes have their unique advantages and limitations, and the choice between them often depends on the user's specific needs and interests. Reflecting telescopes are often recommended for deep space astronomy, while refracting telescopes are popular for detailed observations of lunar and planetary surfaces.
Maintenance and Care of Your Telescope
Preserving your telescope is just as important as the initial purchase. Use only extremely soft wipes/materials to clean the lens. These wipes are always supplied as standard with Vultus. In addition, store the telescope in a dry and dust-free place. If you handle the telescope with care, it can last for decades.
Frequently asked questions:
-
Which type of telescope is best for a beginner?
For beginners, a refracting telescope is often recommended because of its easy operation and low maintenance. A smaller, portable reflecting telescope can also be a good choice, especially if you are interested in deep space objects. Try the collection of telescopes to see which are and which are not suitable! -
How important is the size of the telescope?
The size, more specifically the diameter of the lens or mirror, is important because a larger diameter can collect more light, resulting in brighter and clearer images. For beginners, a diameter between 70 mm and 130 mm is often a good starting point.
-
What is the difference between a GoTo telescope and a manual telescope?
GoTo telescopes are equipped with computer-controlled motors that can automatically find and track objects in the night sky. Manual telescopes require you to find and track objects yourself. GoTo models are more convenient but more expensive and can be more complicated for beginners.
-
How much should I spend on my first telescope?
You don't have to spend a fortune to get a good telescope. For beginners, prices are usually between 100 and 400 euros. It is important to find a balance between quality and budget.
-
Is it necessary to purchase additional accessories?
While most telescopes come with the necessary basic accessories, consider purchasing additional eyepieces or a Barlow lens for greater magnification versatility. A star chart or planetarium app can also be helpful. -
Where is the best place to observe?
For the best observation experience, find a dark place away from city lights. National parks or remote areas are often good choices. A clear, moonless night is ideal. -
Can I take pictures with my telescope?
Yes, this is called astrophotography. Some telescopes are better suited for astrophotography than others, and you may need a special camera or adapter to take photos. Check out our collection of telescopes to see which are and which are not suitable!
