Telescopes make great gifts for birthdays, the holidays and any occasion. There may have been a time when telescopes were available only at high-end prices, but in this day and age, you can find affordable telescopes in department store shelves. It may surprise you, but the best budget astronomical telescope is not easy to find in brick-and-mortar stores but direct from the manufacturer through reputable online retailers. Here’s how to tell if you have the best product on the market in your hands.

 

The best cheap telescope boasts a sufficiently large aperture

The aperture is considered the most essential element of any telescope. The aperture refers to the diameter of the mirror or the instrument’s light-gathering lens. You will find the dimension of this element on the packaging, at the front part of the tube or near the focuser. The mirror’s diameter or the aperture is commonly expressed in millimeters, or inches in a small number of units. An inch is equivalent to 25.4 mm. You want an aperture of at least 70mm or 2.8 inches or greater in a good telescope.

With a larger aperture, the mirror has greater capacity to gather light, allowing easy viewing of more detail plus fainter objects during observation compared to telescopes with smaller apertures. However, you might be able to sight plenty of celestial objects if you live far from city lights that can interfere with the light-collecting capability of your instrument’s optical components. You may be able to view a variety of faraway galaxies extending beyond our own Milky Way if you use a telescope with an 80mm or 3.1-inch aperture in a dark location. This may be doable in a typical suburban setting where you have a 6- or 8-inch telescope for use. In addition, no matter how obscure or brilliant the night sky is, with a scope boasting lots of aperture, you get more spectacular views compared to when you use a small aperture device.

Do not be fooled by the common ploy manufacturers use by blowing up magnification in their packaging, such as when they say a product comes with 700X high power. In truth, the maximum useful magnification of a telescope is its aperture in inches multiplied 50 times, or the equivalent of twice its aperture in millimeters. Therefore, to get genuine 700X magnification, you’d have to use a 14-inch wide scope and the night should provide perfect viewing conditions.

 

When it comes to scope type, you want the best budget refractor telescope you can find

The most familiar type of telescope is the refractor type, which has a lens at the front of the tube. Refractors are frequently low maintenance but do get pricey with larger apertures. When discussing refractor scopes, bear in mind that an apochromat provides better quality images and thus costs more compared to a similarly sized achromat.

On the other hand, a reflector telescope is characterized by the lens or mirror being found at the rear of the primary tube. The least costly type for a given aperture, a reflector scope needs frequent optical alignment adjustments especially when it gets bumped out of position. This process, called collimation, is simple to do.

Catadioptric or compound scopes employ a combination of mirrors and lenses and feature compact tubes along with a comparatively low weight. The two most popular compound scope architectures are Maksutov-Cassegrain and Schmidt-Cassegrain.

The telescope’s power or magnification is determined by the focal length of its objective. Mathematically, this is determined by taking the focal length of the objective and dividing it by the eyepiece dimension, which is indicated on the barrel. To illustrate: a 30mm eyepiece and a focal length of 600mm yields a 20X magnification, which is 600/30. Most devices include a single or a pair of eyepieces to allow you to change the magnification by simply switching eyepieces to obtain a different focal length.

Pay attention to every product’s mount when looking into the best telescope reviews and ratings

Inarguably the most underrated aspect of a telescope, the mount provides the support to keep the instrument stable. Fortunately, plenty of scopes are packaged with mounts or tripods, with some smaller devices often just having a mounting block that enables attachment to a standard photo tripod via a single screw. Bear in mind though that a tripod that works pretty well when taking family photos may not be stable enough for the more sophisticated application in astronomy. Telescope-specific mounts typically have no single-screw attachment blocks and instead, come with stronger and larger plates or rings.

On some mounts, you can swing the device sideways both ways, as well as up and down, much like how you operate a photo tripod. These types are called altitude-azimuth or alt-azimuth mounts. Dobsonians are reflector scopes with a stylish yet simple wooden platform, which is a novelty form of the alt-az mount. A more elaborate system, an equatorial mount is engineered to track stellar motion through rotation on a single axis. Heavier and larger than alt-az mounts, equatorial mounts can only be properly used if they are aligned at the onset to the North Star or Polaris.

Some models feature small mechanized systems or motors to allow them to follow the movement of objects across the sky with keypad button simplicity. The more sophisticated devices are outfitted as Go To scopes that feature a miniature computer integrated into the hand control. The setup process may be too complicated for some users, so Go To scopes are not popular among astronomy enthusiasts. They need the current time, date and location entered so the instrument can find and track any one of the myriads of heavenly objects. Plenty of newer Go To scopes no longer require that extra step prior to use.
