Best telescope

Which telescope is best?

Staring up at the night sky, it's hard not to get overwhelmed with the sheer size of the galaxy. There are millions of things to look at, but you need the right equipment. If you’ve already started to peer at objects with binoculars, it might be time to upgrade to a telescope.

The right telescope for you largely depends on what you want to study, but the Celestron AstroMaster 70AZ is an excellent gadget to get you going. It's easy to use and powerful enough to see every little detail.

What to know before you buy a telescope

Kinds of telescopes

When most people think of a telescope, they imagine a long tube with an eyeglass at one end. These typical models are called refractor telescopes and are only one type of many. The other popular choice is a reflector telescope, which gathers light through a mirror. There are also compound telescopes, which are wider than others. No matter the telescope type, you’re going to need a telescope bag to safely store and carry it.

The aperture determines what you can see

A telescope’s aperture is one of the most important components. Simply put, the aperture is how large the mirror is on the inside, which is directly related to how much light it can gather. The more light it gathers, the better the details and you can see fainter objects. The aperture is measured in millimeters, and you typically need larger mirrors depending on the surrounding light. 

More darkness increases your enjoyment

The best conditions for using a telescope are in an area that has very little light pollution. For example, in a suburban neighborhood, you won’t see as many stars and galaxies as you would in an open field far away from the city. The size of the aperture can only help you up to a point, after which you might need to go somewhere else for viewing — or invest in a bigger aperture.

What to look for in a quality telescope

Lens and magnification accessories

Looking through a telescope lens is exciting, but you often want to see things in greater detail. Look for a telescope that has a variety of eyepieces and accessories. The most common eyepiece you’ll find is the Barlow lens for three-times magnification and the Infinity eyepiece. There are also eyepiece adapters that increase the magnification of the Barlow lens to 120x.

Automated Go-To feature

It's always a good idea to study the night sky where you live. Make sure that you know which galaxies are where and you can identify the brightest stars. Luckily, you don’t have to pore over maps to see planets and formations; a good-quality telescope should have an automated Go-To feature. Through a handheld remote, you tell the telescope what you want to look at, and after a short calibration, it will automatically turn to align itself with the object. 

Phone attachment and Bluetooth remote

It’s a great experience to look at distant planets or even our moon, but it’s more fun if you can take pictures of it, and a quality telescope may have a mobile phone attachment. It looks similar to a car holder, where the device is held in place over the eyepiece. By using the device’s default camera (and to reduce shaking), a Bluetooth remote will trigger the camera to snap a photo of the celestial body.

How much you can expect to spend on a telescope

The average price of a telescope can vary wildly depending on its capabilities and functions. An entry-level or kids' telescope can retail for $40-$50, while an amateur telescope can retail for $100-$200. Much larger professional telescopes retail for $1,000-$2,000. 

Telescope FAQ

Do you need to know where the stars are before using a telescope?

A. Not necessarily, but it will certainly be advantageous. If your telescope can track objects or automatically point toward them, the work is done for you, but if your telescope doesn’t have the function, it's helpful to at least know where the brightest and most popular objects are.

Do telescopes require batteries to operate?

A. For the most part, they don’t. There are no electronic parts inside the telescope tube or eyepiece. If you're looking at a model that has auto-tracking and a remote, you’ll need to insert rechargeable batteries into the controller.
