The wonders of the night sky have fascinated humans for centuries. Today, telescopes bring these wonders closer, allowing us to explore the cosmos from our backyards. With numerous options available, choosing the right telescope can be daunting. In this guide, we will explore the best telescopes for 2021, helping you find the perfect instrument for your stargazing adventures.

Understanding Telescope Types

Before diving into our top picks, it’s important to understand the different types of telescopes. Each type has its advantages and is suited for specific uses.

Refractor Telescopes

Refractor telescopes use lenses to gather and focus light. They are known for their excellent image quality and low maintenance. These telescopes are ideal for viewing planets and the moon.

Reflector Telescopes

Reflector telescopes use mirrors to collect and focus light. They are often larger than refractors and are excellent for deep-sky observing. Reflectors are typically more affordable than refractors of the same aperture.

Catadioptric Telescopes

Catadioptric telescopes combine lenses and mirrors to offer the best of both worlds. They are compact and versatile, making them great for both planetary and deep-sky observations. These telescopes are often more expensive but provide excellent image quality.

Key Features to Consider When Choosing a Telescope


The aperture is the diameter of the telescope’s main lens or mirror. It determines the amount of light the telescope can gather, affecting the brightness and clarity of the image. Larger apertures provide better views of faint objects but may be less portable.

Focal Length

The focal length is the distance between the telescope’s main lens or mirror and the point where the image is formed. It affects the magnification and field of view. Longer focal lengths provide higher magnification, while shorter focal lengths offer wider fields of view.

Mount Type

The mount type determines how the telescope is supported and moved. There are three main types:

  • Alt-Azimuth: Simple and intuitive, suitable for beginners.
  • Equatorial: Designed for tracking celestial objects, ideal for astrophotography.
  • Dobsonian: A type of alt-azimuth mount, known for its stability and simplicity, perfect for large reflector telescopes.


Portability is important if you plan to travel with your telescope or move it frequently. Smaller, lighter telescopes are easier to transport but may have smaller apertures.

Ease of Use

Consider how easy the telescope is to set up and use. Computerized telescopes with GoTo mounts can automatically locate and track objects, making them ideal for beginners. Manual telescopes may require more effort but offer a more hands-on experience.


Accessories can enhance your observing experience. Look for telescopes that include essential accessories such as eyepieces, finderscopes, and tripods. Additional accessories like Barlow lenses and star charts can also be useful.

Tips for Getting the Most Out of Your Telescope

1. Start with the Moon and Planets

Begin your stargazing journey by observing the moon and planets. They are bright and easy to find, providing a good starting point for learning how to use your telescope.

2. Use Low Magnification

Start with a low magnification eyepiece to locate objects and get a wide field of view. Once you have the object centered, switch to a higher magnification eyepiece for a closer look.

3. Invest in a Star Chart

A star chart or smartphone app can help you navigate the night sky and find interesting objects to observe. They are invaluable tools for amateur astronomers.

4. Join an Astronomy Club

Joining an astronomy club can provide valuable guidance and support. You can learn from experienced astronomers, participate in observing sessions, and gain access to telescopes and equipment.

5. Be Patient and Persistent

Stargazing requires patience and practice. Don’t be discouraged if you don’t see everything right away. With time and persistence, you’ll become more proficient at using your telescope and locating celestial objects.


Choosing the best telescope for 2021 depends on your individual needs and preferences. The Celestron NexStar 8SE, Orion SkyQuest XT8, Meade ETX90 Observer, Sky-Watcher ProED 80mm, Celestron NexStar 4SE, Orion StarBlast 4.5, and Zhumell Z8 are all excellent options that offer a range of features and capabilities.
