  • Buying Your First Visual Telescope| Video


    There’s a vast universe of sights to see in the night sky. While unassisted stargazing can be a lot of fun, a telescope is definitely the best way to get the most out of your viewing experience. If you’re new to the world of astronomy, there are a few things you need to consider when purchasing your very first visual telescope.


    buying your first visual telescope-types

    Firstly, you should be aware of the three basic types of telescopes, which are refractors (which use lenses to bend light into focus,) reflectors (which use mirrors to reflect light into focus,) and catadioptric or compound scopes (which use a combination of lenses and mirrors.) For more information on this subject, check out our video explaining the basic types of telescopes.

    Generally speaking, the basic function of every telescope design is to collect light to make a faraway object more visible. The various scope designs, whether they use lenses, mirrors, or some combination of these, are simply different methods to achieve this goal. Each of these types has its own benefits and considerations, including portability, durability, maintenance, ease-of-use, and budget.


    buying your first visual telescope-types aperture size

    The term “aperture,” as it typically applies to telescopes, is the size of a telescope’s main optical element, whether that be a lens or a mirror. As a rule, larger aperture scopes are typically the best way to view widefield and deep sky objects like galaxies and nebulae. At the same time, smaller scopes are great for observing solar system objects like the moon, Jupiter, and Saturn.

    buying your first visual telescope-types aperture size

    Since aperture is tied to the size of the scope in this way, a lower aperture telescope will usually cost less than a higher aperture scope of the same type.


    Another important aspect of telescopes to consider is “maximum magnification,” which represents the highest degree to which you can enlarge the image before the view starts to become blurry.

    maximum magnification different scopes

    In most cases the maximum magnification of a telescope is 50x per inch of your scope’s aperture. The larger the aperture, the larger the useful image you can see. Following this 50x magnification rule, a 2” aperture scope will have a maximum useful magnification of 100x, whereas a 10” aperture scope will have a maximum useful magnification of 500x.

    9mm eyepiece low number equals high magnification

    In order to reach the magnification you need, you will have to attach an eyepiece to your telescope. The lower the rating of the eyepiece in millimeters, the more it will magnify your scope’s view. Since certain magnifications are better for viewing certain objects, it’s usually a good idea to have a handful of eyepieces with different powers to let you view a wide array of objects.

    same magnification with differing apertures

    Just be sure that your desired magnification does not exceed your scope’s maximum magnification, since pushing a small scope beyond its limit just to see a faint object won’t actually help you see it any better. If you’re struggling to get the useful magnification you want with a small scope, you might need to upgrade to a larger aperture scope.


    A good selection of starting eyepieces that should work with a wide range of scopes would be, a 9mm, a 20mm, and a 32mm eyepiece.

    2x barlow

    It would also be a good idea to pick up a 2x barlow, as this can be used to double the magnification of an eyepiece. These should give you a good range of available powers, but you might possibly need a different set of eyepieces depending on your telescope or what you want to see.


    So, with these basics in mind, what are some good telescope choices for beginners?

    refractor telescope

    If you’re on a budget and just want to do basic nearby solar system observing of the moon and the planets, a small refractor is a great value. A quality entry-level refractor scope will usually be in the range of 3-5 inches of aperture with packages starting at around $100. These are highly portable and rugged, and can be used for both nighttime and daytime viewing.

    reflector telescope dobsonian

    If you’d prefer to look at deep sky objects like galaxies and nebulae, a great option is a Dobsonian reflector with an aperture of 6-10 inches. These scopes are both very powerful and great for beginners. They are one of the simplest types of telescopes to use, as simply pointing the optical tube in the direction you want to look is enough to move the scope’s view. On top of that, they are also very affordable, with quality options as low as $200.

    catadioptric telescope schmidt-cassegrain

    If you’re looking for a scope with even higher optical quality, a catadioptric telescope, makes for a great investment. Packing a lot of optical power into a compact package, a compound scope is a great pick-up-and-go scope for observing in a variety of locations and situations.


    Depending on the scope you choose, you may also need to consider what kind of mount you need for it. You’ll need to make sure that you have a mount with enough load capacity to hold up your telescope, along with all of your accessories.

    mount accessory tray

    However, there are many telescope package available which include a mount that will support the scope it comes with, along with more than enough accessories to get you started.


    These are just a handful of things to consider when purchasing your first telescope for visual observing. Ultimately, what you choose is up to you and the type of observing experience you want. If you have any questions or want to know more, you can contact the experienced staff at OPT. We’ll be glad to share our expert knowledge with you and help you get the visual scope that’s right for you. Happy observing!

  • Basic Telescope Types | Video



    If you're new to the world of astronomy it's important to learn the basic telescope types. Most any telescope you get will fall into one of three categories: refractors (which use lenses to bend light into focus,) reflectors (which use mirrors that reflect light into focus,) and catadioptric or compound scopes, (which use a combination of both lenses and mirrors.) While you might hear other specific terms for telescope types mentioned, such as “Dobsonian” or “Schmidt-Cassegrain,” most of these other types are actually variants of the basic three, such as a Dobsonian being a type of reflector or a Schmidt-Cassegrain being a type of catadioptric.


    the basic telescope types refractor light path diagram animation


    Refractors utilize specially designed lenses to focus the light into an image. They are usually long relative to their size, as the light must flow in a straight path through the telescope tube to the eyepiece. The larger the lenses in a refracting telescope, the longer the optical tube has to be to bring the image into focus. This combined with the fact that large lenses can be difficult and expensive for glassmakers to manufacture at high quality means that larger refractors can get rather expensive. For this reason, most refractors available for purchase tend to be smaller than other types, making refracting telescopes one of the most portable types of telescopes on the market.


    the basic telescope types chromatic aberration refractor doublet

    Depending on the type of lenses used for the optics, you may encounter visible color fringing at high magnifications. Also known as chromatic aberration, color fringing is when the various colored wavelengths of light get split from each other and arrive at slightly different angles, showing up as an image with distinct coloration at the edges. Most low-cost refractors are “doublets,” which may have color fringing, whereas “triplet” refractors are designed to eliminate this issue.

    Still, whether a doublet or triplet, refractors are solidly built scopes. Their non-movable lenses make for a sturdy design that doesn’t need much maintenance beyond the occasional cleaning.


    the basic telescope types reflector light path diagram animationReflectors use mirrors, which causes light to reflect at various angles within the optical tube, extending the overall light path. This often causes reflectors to be shorter than refractors of the same aperture, as the light doesn’t need to flow in a straight line to move the same distance. When combined with how manufacturing large mirrors is often cheaper than manufacturing large lenses, it’s fairly common for reflectors to be much less expensive than refractors at larger apertures. Additionally, reflectors are not susceptible to color fringing in the same way that doublet refractors are. If you’re looking for a lot of bang for your buck in terms of aperture, reflectors are a great way to go. This is especially true for Dobsonians which come with their own easy-to-use rocker-box mount.

    Reflectors can be a great value with many conveniences. They can also come in a variety of sizes and can get quite large. With this in mind, purchasing the largest reflector you can afford is a great low-cost way to get a high-aperture scope. Just make sure you are able to store and transport it safely.

    the basic telescope types reflector flip view upside down


    the basic telescope types red dot finder

    There are some things you should consider about the reflector design. By default, the image you see through a reflector’s eyepiece will be upside down. For this reason, you’ll want to use your scope’s finder to line it up with the objects you want to see before looking through the eyepiece. Most modern reflecting telescopes come with a finder scope or a red dot finder, so you most likely won’t have to make an additional purchase to acquire this.

    the basic telescope types reflector collimation demonstration mirror alignment

    Additionally, a reflector will sometimes require a process called collimation, which consists of adjusting the reflector’s mirrors to make sure they stay in proper alignment with each other.

    When properly maintained, a large reflector is a great way to view smaller or far away objects with great clarity and is a great value for achieving high-aperture viewing.


    the basic telescope types catadioptric compound light path diagram animation_maksutov-cassegrain

    Catadioptrics combine the optical benefits of both lenses and mirrors into a compact, convenient package, being smaller and more portable than either refractors or reflectors of the same aperture. This is made possible by the corrector plate that folds the light path and the curved secondary mirror that magnifies the light internally. There are many variations on this design, including Schmidt-Cassegrain and Maksutov-Cassegrains.

    Since it uses mirrors much like a reflector, a catadioptric scope will require collimation. However, unlike with reflectors, this procedure needs to be performed far less frequently. If well taken care of, a compound scope can go for years without requiring collimation.

    The catadioptrics’ small size and portability give them a convenience not found in reflectors of the same class, making them a great investment for both beginners and experienced astronomers alike.


    So which scope is right for you? In most cases, you’re going to want the largest telescope that you can reasonably afford and carry. However, you might have specific needs that could make one scope or another more worthwhile for you personally.

    If you want to do deep-sky observing or wide-field astrophotography of distant galaxies and nebulae, you might want to consider picking up a large reflector.

    If you want a high degree of flexibility in what you observe, a Schmidt-Cassegrain or other compound telescope will give you a lot of options for how to target your viewing and imaging experience.

    If you carefully weigh their benefits and considerations, while also keeping your budget in mind, you should be able to choose a scope that will help you get the most enjoyment you can out of the night sky.
