That is why we have delved into details on the key features you should focus on when shopping. We also explain the value you can get out of these affordable models, and answer the most commonly asked questions.
A telescope in this price range will enable you to view planetary details like shadows and texture of the moon, nebulae and galaxies, among other objects. The number of details will mainly vary according to the diameter size of the aperture and the power of magnification. You can further enhance magnification with a Barrow lens. Generally, the telescope will feature an optical tube, eyepieces, lenses, a focuser, finderscope, a mount, and a tripod. A tripod and counterweights are usually included with equatorial mounts, but altazimuth mounts do not require them at all times.
These are the main features we assessed when comparing different models to come up with our best telescope under $500 list. Taking them into consideration will ease the burden of choice.
There are three major types of telescopes: reflectors, refractors, and compound, also known as catadioptric.
Reflectors gather and focus light using mirrors instead of lenses, which makes them prone to misalignment and interference by natural elements due to the open tube design, but prevents the chromatic aberration common with lenses. The secondary mirror can obstruct light and cause diffraction spikes. Reflectors, such as SkyWatcher S11610, are the best for deep sky exploration because they feature large apertures which produce bright images and a fast focal ratio which offers wide views of galaxies and nebulae.
Refractors gather and focus light using lenses that are fixed so there is no need for alignment or collimation. However, lenses can cause color fringes and distortions. The eyepiece is positioned at the lower end of the tube. Refractors generate clear and sharp images because there is no obstruction of light to the eyepiece by a secondary mirror, and the closed tube design prevents natural elements from affecting the lens. The high quality of images makes refractors ideal for observing the moon and planets, as well as for astrophotography.
Catadioptric telescopes are a hybrid of reflecting (catoptrics) and refracting (dioptrics) telescopes. They combine lenses and mirrors to gather and focus light, and most of them come with computerized functionality. This versatility makes them suitable for both astrophotography and deep sky exploration. Their compactness improves portability and storage. Telescopes of this type are usually somewhat expensive and are not included in our list.
Aperture refers to the diameter of a telescope’s main lens or mirror. The quality of a telescope is defined by its aperture’s light gathering ability, focal length, and its eyepiece’s magnification power. Since observation of celestial objects is complicated by their dimness, a telescope’s ability to brighten them matters much more than its ability to magnify.
Aperture is the most important feature you should prioritize because, unlike eyepieces which can be replaced or added for more power, an aperture does not give you the same option to adjust your choice, so make sure you get it right. Another reason to take apertures more seriously is because they determine the maximum limit of your telescope’s magnification. The larger the aperture, the higher magnification it can accommodate.
An aperture also dictates the amount of details you can view and the level of image brightness and resolution. This is particularly handy when viewing faint and distant objects, such as galaxies and nebulae. The large 203 mm aperture with powerful light gathering ability is what makes the SkyWatcher S11610 so effective in exploring the deep sky and extraterrestrial terrains.
Focal length refers to the distance from the main optical component where light is gathered to the point where it is brought to a focus for the eyepiece to form an image. This obviously influences the level of magnification. A long focal length has higher magnification but offers narrower fields of view than a short one. It is suitable for objects that are closer like the moon, stars and planets. To observe distant galaxies, choose a telescope with a short focal length and large diameter that provide wider and brighter views.
Focal length is closely associated with focal ratio which is denoted by f/number. Focal ratio is the focal length divided by the aperture diameter. A ratio of f/11 to f/15 has high magnification and narrow fields of view while a ratio of f/4 or f/5 has lower magnification, brighter images and wider fields of view suitable for dim and distant objects.
Please note that the focal length is different from the actual length of the telescope. Some models feature designs that can fit a long focal length in a short tube.
A sturdy and stable mount provides support for your telescope, allows smooth mobility, and dampens vibrations to keep it steady for objects to stay in view. It also helps locate and track celestial objects. Choosing the best mount will be based on its portability, payload, and your astronomy intention, whether scoping or focusing. Investing in a good mount will give you years of use even after you have upgraded your telescope.
Altazimuth and equatorial are the two most common types of mounts.
Altazimuth mount has a simple design that is portable and easy to set up, with no need for counterweights. It features two axes with vertical and horizontal movements which can easily locate objects. However, the linear movements are inconvenient for tracking objects as they drift along the sky in an angular arc. After zeroing in on an object, finer adjustments are made using slow motion controls.
Equatorial features two axes, with one aligning to the sky for smooth tracking of objects, an important requirement in astrophotography. The setting circles allow you to locate known objects using coordinates. The mount is usually attached to a stainless steel tripod that may have diagonal bracing to fortify it and an accessory tray. Others are motorized with automated tracking and databases of thousands of viewable objects that you can locate by keying in their coordinates. Equatorial may also have a bubble level and counterweights for balance. The heavy material and multiple items provide stable support with a large payload, but add to the overall weight which makes them inconvenient to transport. The polar alignment during installation can also be confusing for beginners.
An eyepiece uses the light gathered and focused to magnify objects and generate images. Most models include one, or two eyepieces with one optimized for wider field views and the other for higher magnification. The focal length of both the telescope and the eyepiece influences the level of magnification. To calculate eyepiece magnification, divide the telescope focal length by the eyepiece focal length.
Eyepieces with shorter focal length have higher magnification. That means a 10 mm is more powerful than a 25 mm. A Barlow lens is inserted into the focuser to double or triple the eyepiece magnification power.
Always start with the low power eyepiece when scoping because low magnifications provides wide surface area of objects to view, then use the high power eyepiece for focusing once you narrow down on an object. It is worth noting that high magnification does not always produce better images. In distant objects, it actually makes them blurry because the light is spread out thin.
Since stargazing and celestial adventures take place outdoors, you will need a telescope that you can easily move outside and store away afterwards. Most of the telescopes are light and compact. It is the mounts, steel tripods, counter weights and additional accessories that make the entire set bulky.
Knowing the size and dimensions of the telescope will help you determine its portability and compare it with payload when shopping for a mount. Additional accessories include software, such as the Starry Night in Orion 09007 and the SkyX in Celestron NexStar 127SLT; database of celestial objects; instructional DVDs and manuals; and an accessory tray. Since telescopes are long-term investments, a long warranty is also an essential feature to consider.
