Adult’s telescopes – Buying guide & Comparison

 

If you’re short on time and you just want to find the best telescope for adults, this short paragraph should help you get exactly the model you need. We have been able to gather plenty of information that has enabled us to compare products based on product surveys, actual owner feedback and ratings and reviews in expert review sites for this type of product. According to our findings/research, the Orion 10015 StarBlast is the best because of its innovative compact grab-and-go design that makes it the perfect tool for entry-level and intermediate astronomy enthusiasts. Boasting a generous 4.5-inch aperture, this instrument comes with a speedy focal ratio of f/4 to deliver bright, detailed views of our Solar System’s components such as the Moon and planets, along with farther objects such as star clusters and nebulae. Its stable tabletop base delivers remarkable altazimuth motion to enable easy manual tracking of celestial objects as they move across the sky. If the Orion 10015 StarBlast is unavailable, your second option should be the Orion 9024 AstroView.

 

The telescope is indisputably the tool of choice whether for beginner-level or intermediate-level celestial observations. A good quality telescope offers convenience and dependable performance using award winning telescope capabilities and features. How can you distinguish the best telescope for adults from the inferior ones on the market?

 

The best telescope for viewing planets and galaxies comes with an optimally large aperture

The power of the telescope is determined by the size or diameter of the mirror or its light-collecting lens. This is simply known as the instrument’s aperture. The aperture is specified in the product’s package, and is also indicated at the front part of the tube and sometimes, near the focuser. The aperture or lens/mirror diameter is commonly expressed in millimeters and sometimes in inches. One inch is equal to 25.4mm. An aperture of at least 70mm or 2.8 inches or higher is preferred in any decent quality telescope.

A larger aperture means the mirror or lens has a higher capability for light gathering, providing greater detail in viewed objects. This also enables you to view fainter objects with greater detail than when using low aperture telescopes. You might view a huge number of deep sky targets in locations far from the lights of the city. Electric lights tend to interfere with the light-gathering ability of the optical components of a telescope. An 80mm or 3.1-inch aperture telescope lets you observe galaxies beyond our own especially in dark locations. In suburban settings, you can do this using a 6- to 8-inch telescope. Regardless of the intense brightness or darkness of the night sky, a high-aperture instrument lets you achieve exceptional views as against using a telescope with a small aperture.

Magnification, no matter how manufacturers blow it up in their products’ boxes, is not a reliable indicator of a scope’s power. Some manufacturers of cheap telescopes place too much emphasis on this element by using awe-inspiring numbers such as 500x magnification and the like. Technically, the maximum useful magnification of the device is 50 times the aperture in inches, which is equal to the aperture in millimeters taken twice. Thus, if you are to genuinely obtain 500x magnification, two conditions should be met: the viewing conditions should be perfect and free from air currents, and you will have to use a 10-inch scope as well.

Magnification is calculated using the focal length of the scope’s objective. Take the focal length and divide it by the dimension of the eyepiece, which can be found on the eyepiece barrel. Thus, if you have a focal length of 750mm and a 25mm eyepiece, you can achieve a 30x magnification, or the value obtained from 750/25. Plenty of models include one or two eyepieces in the package, enabling you to switch magnifications by changing the eyepieces to get a different focal length.

 

Consider the type of product in the best telescope reviews that you can easily work with

Telescopes on the market typically come with a refractor optical design. A refractor scope features a lens at the front of the tube. Typically requiring minimal maintenance, a refractor scope tends to fetch a higher price because of its typically large aperture. Apochromatic scopes help you achieve better quality images and this means higher acquisition costs than comparatively sized achromatic scopes.

Reflector scopes have the mirror or lens at the rear of the primary tube. Reflectors cost the least for a given aperture. They also require diligent adjustments to their optical alignment most especially when they are accidentally bumped askew. Adjustment of the optical alignment is simply known as collimation and is relatively simple to perform.

Compound or catadioptric telescopes utilize a network of lenses and mirrors. They come with compact tubes plus a relatively lightweight design. Maksutov-Cassegrain and Schmidt-Cassegrain.are the most widely-used catadioptrics.

The best beginner telescope for adults comes with a robust mount

The mount frequently gets the least attention but it is in fact of prime importance. A lot of models ship with their own tripod or mount. Smaller models typically come with a mounting block that accommodates a standard tripod for photography using a screw. Please remember though, that what might work for photography may not be suitable for astro-imaging or astrophotography. Mounts designed for telescope use feature larger and more rigid plates or rings and not just attachment blocks with single-screw designs.

Some mounts enable horizontal swinging of the scope as well as up and down orientation adjustments just like a standard photo tripod. These are called altitude-azimuth mounts, or simply altazimuth or alt-az mounts. A version of the altazimuth mount is the wooden platform of Dobsonians.

The equatorial mount is a more sophisticated type of mount and is designed to track the movement of the stars across the sky. An equatorial mount is larger and heavier than alt-az ones, and can only be properly used after correct alignment with Polaris or the North Star. Some equatorial mounts are driven by a motor to enable them to follow the movement of celestial objects under observation through buttons on a keypad controller.
