Telescope FAQ
How do I choose the right telescope for me?
Choosing the perfect telescope, especially as a beginner, can feel overwhelming due to the technical jargon and numerous options available. However, significant advancements in telescope quality in recent years mean most models perform reasonably well. The key is finding the one that best suits your specific needs.
The most crucial factor is the optical quality, which affects the clarity and sharpness of the views. You also need to consider the aperture size (how much light it gathers), the type of mount (manual, alt-azimuth, equatorial, computerized), and whether you need a portable instrument or a more powerful, larger one for a fixed location. Beginner telescopes are specifically designed to ease newcomers into the hobby.
Beyond the hardware, think about your observing goals: what objects do you want to see (Moon/planets vs. deep space)? Where will you primarily observe from (light-polluted city vs. dark rural site)? Are you interested in astrophotography? Your budget is also a significant factor.
It’s highly recommended to purchase from reputable telescope dealers. They offer reliable products, often with warranties, and their staff typically possess expertise to guide you towards the right decision.
What types of telescope are there?
There are three primary types of telescopes: reflectors, refractors, and catadioptrics.
Reflector telescopes use mirrors to collect and focus light, while refractors use lenses. Catadioptric telescopes combine both mirrors and lenses. Each type has variations; for instance, Newtonian telescopes are a basic type of reflector, often found on simple alt-azimuth or Dobsonian mounts.
For the best value in terms of aperture size, Newtonian reflectors on a Dobsonian mount are often recommended. These are manually operated telescopes and require using star charts to navigate the sky. They gather a lot of light and provide impressive views of many celestial objects. However, larger Dobsonians can be quite bulky and require storage space.
Adding a computerized or equatorial mount increases the cost significantly but offers automated tracking or object finding (GoTo). Computerized Dobsonians or Newtonian telescopes with GoTo capabilities are available, offering convenience at a higher price. A premium Newtonian on a German equatorial mount is much more expensive but offers high precision for tracking and astrophotography.
If portability, ease of use, and convenience are priorities, a smaller refractor (up to 4 inches) or a catadioptric (Schmidt- or Maksutov-Cassegrain up to 5 inches) on a computerized mount are good choices. These are versatile and provide high magnification suitable for observing the Moon and planets.
Achromatic refractors, especially shorter focal length ones, can show false color fringing around bright objects because they don’t focus all wavelengths of light perfectly. Maksutov-Cassegrains are better at correcting chromatic aberration, providing clean, high-contrast views. Apochromatic refractors use special glass to virtually eliminate false color, offering the best refractor views, but they are considerably more expensive.

How does a refractor telescope work?
Refractors operate by bending (refracting) light through a lens system to form an image, which is then magnified by an eyepiece. With their simple design and low maintenance, refractors are popular, especially for observing the Moon and planets.
A refractor has a main objective lens at the front and a star diagonal with an eyepiece at the back. They are typically mounted on alt-azimuth mounts for easy manual control. This straightforward design makes them relatively easy to manufacture, contributing to their affordability, particularly for novice models.
However, producing high-quality, large-aperture lenses is expensive, so refractors become significantly pricier as the aperture increases. This also makes basic refractors a target for low-quality reproductions from less reputable vendors, so caution is advised when purchasing.
Refractors are known for delivering high-contrast, magnified images, making them excellent for viewing solar system objects like the Moon, planets, and double stars. A refractor with an aperture of 2 inches (60mm) or more offers reasonable views, while 3 to 4 inches (80mm – 90mm) provides better performance for a serious hobby telescope.
A common drawback is chromatic aberration, or “color fringing,” where bright objects show a colored halo because different light wavelengths don’t focus at the exact same point. Achromatic refractors reduce this, while more expensive apochromatic (APOchromatic) refractors use specialized glass to nearly eliminate it. Even with achromatic designs, some purple fringing may remain, but for most casual observing, it doesn’t significantly detract from the experience. Apochromatics offer stunning, color-free views but come at a much higher price. Some high-end apochromatics might even require buying a tripod separately.

How does a reflector telescope work?
Reflector telescopes use mirrors to collect and focus light. The two most common types are the Newtonian and the Dobsonian, which share the same optical principle.
A Newtonian telescope has a large curved primary mirror at the bottom of the tube that collects light. This light is reflected back up the tube to a smaller, flat secondary mirror positioned at a 45-degree angle, which then directs the light out to the eyepiece located near the front of the tube.
Newtonian reflectors can be found on various mounts, including alt-azimuth and equatorial mounts. Equatorial mounts are popular for their ability to track the apparent movement of celestial objects as the Earth rotates, making them suitable for both visual observing and astrophotography. Reflectors are favored by many in the amateur astronomy community for their versatility and the fact that you generally get more aperture for your money compared to refractors. For example, an 8-inch (203.2mm) reflector typically costs less than a refractor of the same aperture, offering greater light-gathering power and resolving capability at a lower price point, making it a common choice for the best amateur astronomer telescope value.
Newtonian reflectors do require periodic maintenance, mainly collimation (aligning the mirrors) to ensure optimal performance. The mirrors may also need cleaning or recoating over time. Choosing a model with protective mirror coatings helps extend their life and ease maintenance.
The Dobsonian telescope is a type of Newtonian reflector on a very simple, easy-to-use alt-azimuth mount. They are known for providing large apertures at low cost and are very intuitive to maneuver. While they don’t track automatically, their simplicity and light-gathering power make them excellent for visual observing, particularly of faint deep-sky objects like galaxies and nebulas. Computerized or GoTo Dobsonians and Newtonians are available for automated object finding, but they are more expensive.
Whatever the mount type, reflectors are particularly effective for wide-field views of extended objects like galaxies and many nebulas.

How does a catadioptric telescope work?
Catadioptric telescopes, also known as compound telescopes, combine the optical principles of both refractors (lenses) and reflectors (mirrors) to create a compact and versatile instrument. They use a primary mirror, a corrective lens, and a secondary mirror to produce an image. This hybrid design allows for longer focal lengths and higher magnifications within a relatively short optical tube, making them more portable than traditional refractors or reflectors of equivalent focal length. They are often considered ideal for astrophotography and observing a wide range of celestial targets. Their sealed optical tubes require minimal maintenance. The main drawback is that they tend to be more expensive than similarly sized reflectors or refractors, though shopping around can yield good deals.
The two most common types are the Schmidt-Cassegrain and the Maksutov-Cassegrain.
The Maksutov-Cassegrain (“Mak”) is known for correcting optical aberrations like coma (which distorts star shapes) and chromatic aberration (color fringing). It uses a spherical primary mirror and a deeply curved meniscus corrective lens at the front of the tube. This design provides sharp, high-contrast views, making Maks particularly strong for observing planets, the Moon, and double stars. Maksutov-Cassegrains often feature GoTo mounts, simplifying navigation for the user.
The Schmidt-Cassegrain is another popular catadioptric design, using a spherical primary mirror and a Schmidt corrector plate at the front. Like Maks, they offer compact size and versatility. Schmidt-Cassegrains are also commonly available with GoTo systems. They are excellent for general observation of planetary and deep-sky objects. Corrector lenses can be added to widen their field of view for extended targets.
Both types offer high magnification capabilities in a portable package and are frequently equipped with computerized GoTo mounts, making them excellent choices for a feature-rich amateur astronomy telescope.

What is a finderscope?
A finderscope is a small, low-magnification telescope or sight mounted parallel to your main telescope’s optical tube. Its purpose is to help you locate celestial objects more easily. Because your main telescope typically has a high magnification and a narrow field of view, finding a specific target can be challenging. The finderscope, with its much lower magnification and wider field of view, shows you a larger area of the sky.
To use it, you first align the finderscope with your main telescope. Then, look through the finderscope to scan the broader area of the sky where your target is located. Once you spot the object in the finderscope’s wider view, you maneuver the telescope until the object is centered in the finderscope’s crosshairs or reticle. When it’s centered in the finderscope, it should then be visible in the main telescope’s eyepiece.
Many telescopes come packaged with a finderscope. There are two main types: straight-through (you look directly along the line of sight) and right-angled (you look through an eyepiece positioned at a 90-degree angle). The choice often depends on the type of main telescope you have and ergonomic preference. Some finderscopes also include correcting prisms to show an “erect image” (right-side up and not reversed), which can be less disorienting for beginners compared to inverted or reversed views.
What does aperture, magnification and focal length mean on a telescope?
Understanding these terms is essential when choosing a telescope.
Aperture refers to the diameter of the main light-gathering component of the telescope – either the objective lens (in a refractor) or the primary mirror (in a reflector or catadioptric). A larger aperture collects more light, allowing you to see fainter objects and reveal finer details. For example, a 200mm aperture telescope collects four times more light than a 100mm telescope and can resolve smaller details (e.g., a 1.5km lunar crater vs. a 3km crater) and see fainter stars. Aperture is the most critical factor determining a telescope’s performance.
Focal length is the distance from the main lens or mirror to the point where the light converges and forms a focused image. Telescope focal length is a fixed property of the instrument. It’s typically measured in millimeters. Longer focal lengths generally result in higher magnification when used with the same eyepiece, while shorter focal lengths offer wider fields of view.
Magnification is the amount by which an object appears larger through the telescope compared to viewing it with the naked eye. Magnification is not a fixed property of the telescope alone; it depends on both the telescope’s focal length and the focal length of the eyepiece you are using. The formula is: Magnification = (Telescope Focal Length) / (Eyepiece Focal Length). Eyepieces have different focal lengths, allowing you to change the magnification of a given telescope.
The “useful magnification range” of a telescope is limited by its aperture and the seeing conditions (atmospheric stability). There’s a point where increasing magnification simply magnifies atmospheric turbulence and image imperfections, resulting in a blurry view. A common rule of thumb for the maximum useful magnification is about 50x per inch of aperture (or 2x per millimeter), though this is often limited by atmospheric conditions. Too low a magnification can also be inefficient, as the “exit pupil” (the beam of light leaving the eyepiece) may become larger than your eye’s pupil, wasting light.

Telescope eyepieces can be swapped to change the magnification. (Image credit: Jamie Carter)
Magnification: How do telescope eyepieces work?
Eyepieces are critical accessories that determine the magnification and field of view you experience through a telescope. They work by taking the light focused by the telescope’s main lens or mirror and magnifying that image before it reaches your eye. Every telescope eyepiece has a specific focal length, measured in millimeters (mm). A shorter eyepiece focal length results in higher magnification, while a longer eyepiece focal length provides lower magnification but a wider field of view.
As mentioned before, magnification is calculated by dividing the telescope’s focal length by the eyepiece’s focal length. For example, a telescope with a 1000mm focal length (like a 100mm f/10 refractor or a 200mm f/5 Newtonian) will produce 100x magnification when used with a 10mm eyepiece (1000mm / 10mm = 100).
While you can achieve very high magnifications using very short focal length eyepieces, there’s a limit to how much detail can be resolved. Pushing magnification too high magnifies not only the object but also atmospheric turbulence (seeing) and optical imperfections, leading to a degraded image. High magnification is only practical when atmospheric conditions are very steady and with telescopes on driven mounts that track objects.
A good starting point for an amateur astronomy telescope setup is usually a set of at least three quality eyepieces offering low, medium, and high magnifications. For a 100mm f/10 telescope (1000mm focal length), this might be a 20mm eyepiece (50x magnification, wide field), a 10mm eyepiece (100x magnification, medium field), and a 5mm eyepiece (200x magnification, high power). Lower magnification eyepieces are useful for finding objects and viewing large deep-sky areas, while higher magnification eyepieces are used for detailed views of the Moon, planets, or splitting double stars when conditions allow.
