Introduction
With so many telescopes available, it’s hard to know which one is best for you. Here’s a guide to the best telescopes for amateur astronomers like you.
Embark on a thrilling journey of discovery with refractor telescopes. These telescopes, akin to magnifying glasses, harness the power of lenses to gather and focus light. They’re an exciting starting point for beginners, offering a gateway to the mysteries of the universe with their ease of use and maintenance.
Moreover, they unveil the moon, planets, and even deep-sky objects like galaxies and star clusters in awe-inspiring, precise detail, igniting a sense of wonder and curiosity.
Refractor Telescopes
Refractor telescopes, also known as dioptric telescopes, work on a different principle than reflector telescopes. Instead of using mirrors to gather and focus light, refractor telescopes use lenses.
The main components of a refractor telescope are the objective lens, the eyepiece, and the telescope tube. The objective lens is a large, curved lens at the front of the telescope. When light from distant objects enters the telescope, it passes through the objective lens, which bends or refracts the light and brings it to a focus point inside the telescope tube.
The eyepiece is where you look to see the magnified image of the object you’re observing. It contains additional lenses that further magnify the image produced by the objective lens.
Simplicity and Ease of Use
Refractor telescopes are prized for their simplicity and ease of use. They have a sealed tube, which helps protect the lenses from dust and moisture, making them low-maintenance and durable.
One of the advantages of refractor telescopes is their excellent image quality. Because they use lenses to focus light, refractor telescopes are free from optical aberrations like coma and astigmatism, which can affect the image quality in reflector telescopes.
Capturing Fine Details
Refractor telescopes are also great for observing bright objects like the moon, planets, and double stars. Their high contrast and sharpness make them ideal for capturing fine details on the surfaces of celestial objects.
However, refractor telescopes do have some limitations.
They tend to have smaller apertures compared to reflector telescopes, which means they gather less light and may not perform as well when observing faint objects like galaxies and nebulae.
Additionally, refractor telescopes of similar aperture size can be more expensive than reflector telescopes, especially those with high-quality lenses made from specialized glass materials.
Popular Among Amateur Astronomers
Despite these drawbacks, refractor telescopes remain popular among amateur astronomers for their excellent image quality and ease of use. Whether you’re a beginner or an experienced stargazer, mastering the use of a refractor telescope can provide a sense of accomplishment and hours of enjoyment in exploring the wonders of the night sky.

One popular choice among amateur astronomers is the Celestron PowerSeeker 80AZ. This telescope is not only affordable but also lightweight, making it a perfect companion for your night sky explorations.
Next, we have reflector telescopes. Instead of lenses, these telescopes use mirrors to capture and reflect light. They’re excellent for viewing faint objects in the night sky, thanks to their larger apertures.
Reflector Telescopes
A reflector telescope, also known as a Newtonian telescope, uses mirrors instead of lenses to gather and focus light. The main components of a reflector telescope are the primary mirror, the secondary mirror, and the eyepiece.
The primary mirror is the heart of the telescope. It’s a large, curved mirror that sits at the bottom of the telescope tube. When light from distant objects enters the telescope, it strikes the primary mirror and reflects toward the secondary mirror.
The secondary mirror is a smaller mirror mounted near the top of the telescope tube. Its job is to intercept the light reflected by the primary mirror and redirect it toward the eyepiece, which is where you look to see the magnified image of the object you’re observing.
Reflector Telescope’s Large Aperture
One critical advantage of reflector telescopes is their large aperture. The aperture, which is the diameter of the primary mirror, is a crucial factor in determining how much light the telescope can gather. More light means brighter and clearer images, especially when observing faint objects like distant galaxies and nebulae.
In simple terms, a larger aperture allows more light to enter the telescope, resulting in a brighter and more detailed view of the celestial object.
Because reflector telescopes use mirrors instead of lenses, they are free from chromatic aberration, a common optical problem that can distort images in refractor telescopes. Chromatic aberration occurs when different colors of light focus at various points, resulting in a blurred or fringed image. It means that reflector telescopes can provide sharper and more detailed views of celestial objects.
Drawbacks with Reflector Telescopes
However, reflector telescopes do have some drawbacks. They require occasional collimation, which is the process of aligning the mirrors to ensure optimal performance. Collimation might sound complicated, but it’s a straightforward procedure that involves adjusting the position of the mirrors to maintain their alignment. With a bit of practice, it can be quickly learned and becomes a routine part of keeping your telescope.
Additionally, reflector telescopes can be bulky and require a sturdy mount to support the weight of the telescope tube and mirrors. This is especially true for larger reflector telescopes with larger apertures.
Reflector Telescopes Excellent Performance and Affordability
Despite these challenges, reflector telescopes are popular among amateur astronomers for their excellent performance and affordability. They can reveal the wonders of the universe in stunning detail, making them a fantastic choice for anyone looking to explore the night.

These compact telescopes sit on sturdy mounts and are ideal for stargazing on the go. The AWB OneSky Telescope is a favorite among amateur astronomers for its excellent optics and affordability. Plus, its compact size makes it perfect for taking to dark sky sites away from city lights.
Computerized Telescopes
Now, let’s talk about computerized telescopes, also known as GoTo telescopes. These high-tech marvels use built-in computers to locate and track celestial objects automatically. They’re perfect for beginners who need help finding objects in the sky on their own. However, it’s important to note that they can be more expensive than manual telescopes, and they require a power source to operate, which may limit their use in remote or dark sky sites.

Here’s how they work:
Alignment:
When you first set up a computerized telescope, you typically need to align it with the night sky. This usually involves pointing the telescope at a few known stars or celestial objects, which the telescope’s computer uses to determine its orientation and location.
Database:
Computerized telescopes come pre-loaded with a database of celestial objects, including stars, planets, galaxies, nebulae, and more. This database is often extensive, containing thousands or even tens of thousands of objects.
Automatic Slewing:
Once the telescope is aligned and knows its position, you can select an object from the database using a hand controller or a smartphone app. The telescope’s computer then calculates the necessary movements and slews (moves) automatically to point the telescope at the selected object.
Tracking:
After the telescope has found the object, it continuously tracks its movement across the sky as the Earth rotates. This tracking is essential for keeping the object centered in the telescope’s field of view, allowing for extended observation and photography.
User Interface:
Computerized telescopes often have user-friendly interfaces, such as hand controllers with menus and buttons or smartphone apps with touchscreen controls. These interfaces make it easy for users to navigate the telescope’s database and select objects to observe and control its movements.
Additional Features:
Some computerized telescopes offer extra features, such as guided tours of the night sky, audio commentary about celestial objects, and the ability to connect to a computer for remote control and astrophotography.
Overall, computerized telescopes are powerful tools that make stargazing and astronomy more accessible to enthusiasts of all skill levels. Automating the process of locating and tracking celestial objects allows users to spend less time searching for targets and more time observing and enjoying the wonders of the universe.
