Buying Guide: How To Choose A Telescope Under $500

Telescopes are an incredible door to the heavens, for anybody intrigued by space and astronomy.

Telescopes are an incredible door to the heavens, for anybody intrigued by space and astronomy and is willing to investigate the unending immensity of the world. If you are looking for the best telescope under $500 then you are bound to encounter a wide variety of choices. The telescopes for under $500 are ideal for amateurs to intermediates to advanced as well. 

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. 

There is a big variation between telescopes used for watching mountains and cities, than those for watching the Moon and neighbouring planets, or the ones for deep space exploration.

thebigbangoptics

What is generally important are good optics for a clear view especially if you are someone interested in astrophotography paired with a stable and secure stand as well.

One common misconception is that telescopes are meant to magnify small objects. The objects in space are certainly not small – they are enormous.

They only appear small to us. And if we only magnify what we can see with our eyes, we would simply get a big smudge with a distorted picture. Imagine this scenario as zooming into a low-quality picture.

What is important is the gathering light capability, the size of the aperture This will allow us to see more details – only then the magnification actually makes sense.

So, while magnifying power is important, it relies on a more significant feature – objective diameter, or aperture.

A bigger aperture allows for greater magnification. But keep in mind that magnification also depends on the focal ratio.

So if you want to look at smaller details with a bigger magnification, you might want to use slow telescopes with a high f-number, instead if you want a wide field of view with lots of stars and galaxies, a fast telescope with a low f-number is a better choice.

Finally, make sure to always double check whether or not your telescope under $500 (it should) comes with a stand because some models do ship without a stand and mount.

You can also consider telescopes with GoTo Mounts, these will help you guide the telescope automatically with a handheld computer.

Features To Look For In A Telescope Under $500

Type Of Telescope

The telescopes, for all their varied shapes and sizes, types of telescopes can be divided into three classes: refractors, reflectors, and catadioptrics.

1. Refractor Telescope

The refractor telescope uses a lens to gather and focus light. The first telescopes built were refractors. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens.

Refractor telescopes are rugged. After the initial alignment, their optical system is more resistant to misalignment than the reflector telescopes.

The glass surface inside the tube is sealed from the atmosphere so it rarely needs cleaning.

Since the tube is closed off from the outside, air currents and effects due to changing temperatures are eliminated. This means that the images are steadier and sharper than those from a reflector telescope of the same size.

All refractors suffer from an effect called chromatic aberration (“color deviation or distortion”) that produces a rainbow of colors around the image. Because of the wave nature of light, the longer wavelength light (redder colors) is bent less than the shorter wavelength light (bluer colors) as it passes through the lens.

2. Reflector Telescope

The second type of telescope, the reflector telescope, uses a mirror to gather and focus light. Its most common form is the Newtonian reflector, with a specially curved concave primary mirror in the bottom end of the telescope.

Near the top a small, diagonal secondary mirror directs the light from the primary to the side of the tube, where it’s met by a conveniently placed eyepiece.

If you want the most aperture for your money, the reflector is the scope for you.

When well made and maintained, a reflector can provide sharp, contrasty images of all manner of celestial objects at a small fraction of the cost of an equal-aperture refractor.

3. Catadioptric Telescope

The third type of telescopes are the catadioptric or compound telescope. These were invented with the desire to combine the best characteristics of refractors and reflectors: they employ both lenses and mirrors to form an image.

The greatest appeal of these instruments is that, in their commonly encountered forms (the Schmidt-Cassegrain and Maksutov-Cassegrain), they are very compact.

Their tubes are just two to three times as long as wide, an arrangement allowed by “optical folding” of the light. The smaller tube can use a lighter and thus more manageable mounting. The upshot is that you can obtain a large-aperture, long-focus telescope that’s very transportable.

Aperture

best telescope under 500

The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror. 

A scope’s aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears). When learning how to choose a telescope, knowing all you can about the aperture is crucial to your ability to see the night sky.

This simply means – the bigger the aperture the better. With a 6-inch telescope you can discern craters on the Moon as small as about a mile across — half the size of those visible in a 3-inch scope (under the same conditions using the same magnification). 

The same two instruments turned toward a faint galaxy on a moonless night would tell an even more dramatic story. Because the surface area of a 6-inch mirror is four times that of a 3-inch mirror, it collects four times as much light, meaning the galaxy would appear four times brighter. 

Focal length

Focal length is 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 will have high magnification and narrow fields of view while a ratio of f/4 or f/5 will have lower magnification, brighter images and wider fields of view suitable for dim and distant objects.

Mounts

The best telescope in the world is useless unless it’s on a solid, stable, smoothly-working mount, one that permits it to be directed to the desired part of the sky and to follow a celestial object smoothly and precisely as the Earth turns beneath it.

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.

1. Altazimuth Mounts

An equatorial mount should be used for a telescope intended for astronomy, and for which astrophotography is a future prospect, the equatorial mount here automatically counteracts Earth’s rotation.

It’s far easier to track a celestial object with a scope mounted this way, since you need only concern yourself with turning the scope about one axis — not two simultaneously, as in the alt-az. When an equatorial mount is properly set up, turning the slow-motion control of its polar axis is all that’s required to keep an object in view.

2. Equatorial Mounts

An equatorial mount should be used for a telescope intended for astronomy, and for which astrophotography is a future prospect, the equatorial mount here automatically counteracts Earth’s rotation.

It’s far easier to track a celestial object with a scope mounted this way, since you need only concern yourself with turning the scope about one axis — not two simultaneously, as in the alt-az. When an equatorial mount is properly set up, turning the slow-motion control of its polar axis is all that’s required to keep an object in view.

Eyepieces

Eyepieces determine the magnification and field of view of a telescope. Different eyepieces are used to view different objects.  

Some objects, such as nebulae and star clusters, appear quite large and are best viewed at low magnifications (which give a wider field of view), whereas planets appear very small and are normally viewed with high-magnification eyepieces.  

One of the most common misconceptions in amateur astronomy is that magnification is the most important aspect of a telescope.  

In reality, the diameter (aperture) of a telescope determines its power and different eyepieces are used to get the best view of a given object.  Often the best view is at a low magnification.  

There are two standard sizes of telescope eyepieces.  The sizes are determined by the diameter of the eyepiece barrel that fits into the telescope.  The two standard sizes are 1.25″ and 2″. 

Weight

The size and weight of the telescope you are willing to carry is probably the biggest problem one must ponder.

Telescopes can range from around 15 lbs. to well over 300 lbs. Most can be broken down into 3 subsections for transportation: the optical tube assembly, the telescope mount, and the tripod or base. Remember, if the scope is too heavy, you may not use it at all.

Magnification

The magnification (power) of a telescope is variable and depends upon the eyepieces one uses. The power is computed by dividing the focal length of the primary objective (aperture) of the telescope by the focal length of the eyepiece being used.

Other Features

It is also important that you consider extra features such as accessories, warranty, instructional DVDs, and more.

Additional features might also include softwares such as StarryNight as in Orion 09007 and SkyX in Celestron NexStar 127SLT, an accessory tray or an extra 3rd eyepiece as with Gskyer AZ90600.

A database of celestial objects, instructional DVDs or Barlow lenses are other accessories that you should look for in a telescope under $500.
