5 Best Computerized Telescopes in 2020 [GoTo & Non-Motorized]

Astronomy technology is becoming more versatile and accessible to astronomy enthusiasts every year. Though they’re not exactly brand new, computerized telescopes are another worthy addition to the world of amateur astronomy. Computerized telescopes are simply standard telescopes (reflector or refractor) that come with a built-in computer and use a GPS system. 

They make navigating the night sky much more manageable, so they’re particularly great for budding astronomers (though they’re great for seasoned veterans as well). While this new tech is pretty exciting, it also makes picking out equipment an even more complicated task, often requiring a fairly intense amount of research to find what you need. 

In this comprehensive guide, we’ll cover everything you need to know before buying a computerized telescopes—what variations there are, if you really need to get one, how much they cost, and what ones are the best at what they do.

Types of computerized telescopes

Computerized telescopes are broken up into two categories, motorized, also known as “GoTo,” and non-motorized.

GoTo telescopes have an electronic motor that’s connected to the included computer, which allows the user to input locations, and the telescope will automatically go to them.

  • They’re user-friendly, sleek, and you don’t have to do things manually.
  • GoTo telescopes are extremely helpful for beginners, but they’re also useful to seasoned enthusiasts seeking to save time as they scan the cosmos.
  • The big disadvantage of a computerized telescope is that it makes things “too easy,” which we really don’t think is that big of a deal! 

Non-motorized versions are similar in that they still have a computer, but you have to manually move and adjust the telescope to the desired location (the computer provides instructions).

  • This could be considered the downside of non-motorized versions, but many argue that the non-motorized versions are better for beginners.
  • They make scanning for objects easier while not providing the motorized “crutch.”
  • Overall, they can both be great for beginners, but non-motorized telescopes offer the opportunity to learn the ropes of the manual adjusting process using guided instructions.

Computerized telescope price timeline

Dissimilar to traditional reflector and refractor telescopes, the price ranges for computerized telescopes are easier to navigate. In general, motorized telescopes are inexpensive and you can typically find a good quality one for under or around $500. 

Under $100 – Anything under $100 is considered a cheap computerized telescope. These telescopes, while very inexpensive, are not typically worth buying—it’s best to spend a bit more and get something with higher quality.

Budget: $100-$300 – Telescopes residing in the $100 to $300 range are typically decent quality, and they’re a good choice if you’re on a tight budget. We recommend getting something around $300 if you can, though.

Mid-range: $300-$600 – This is the perfect range for someone who’s interested in jumping into astronomy, or an intermediate astronomer looking to upgrade their old equipment.

High-end: $600-$1,000 – A higher-end computerized telescope will cost you about $600 or more. Optics and overall viewing quality begin to take a leap-up at this point.

Seasoned Astronomer: $1,000+ – This range is primarily for seasoned astronomers who want to upgrade their viewing experience, and also don’t have too much of a budget. Telescopes in this range provide a gorgeous viewing experience, but that’s why they’re more expensive.

Don’t forget the power source

Before buying a computerized telescope, it’s essential to determine where you’ll be using it most. Where you plan to use, it plays a part in what other accessories you need, especially when it comes to power.

  • These types of telescopes always require electricity to operate (obviously), so you’ll need a stable power source if you want to view the night sky uninterrupted. 
  • If you’re using it at home, for instance, you can simply plug your telescope into an outlet in or outside of your home. However, if you’re using it somewhere remote, you’ll need a portable power supply. 

Both options can affect the overall price and the portability of the telescope. Most portable power sources for telescopes have an adapter that you can plug into your vehicle, but if you’ve ever tried that before, it kind of ruins the experience (you’ll be wondering if your car battery will die the whole time). Adding a portable power source also affects the overall weight of your telescope, which is crucial to remember if you plan on hiking with it!

How to choose the right computerized telescope?

The first things you should always check with a new telescope are aperture, which is the diameter of its primary optical mirror/lens, and focal ratio, which determines narrow or wide viewing capabilities. However, when hunting for a quality computerized telescope, there are two primary questions you’ll need to ask yourself: “Does it have GPS?” and “Are the components well-made?” 

Does it have GPS?

  • A lot of older computer systems don’t have a Global Positioning Device (GPS), meaning you’ll have to go through a manual alignment procedure similar to setting up a regular telescope. 
  • Learning this procedure can be frustrating, but many suggest it’s a worthwhile endeavor because it’s helpful knowledge, and it becomes easier with practice. 
  • If you’d prefer to avoid having to do this 100% manually every time you move locations or set it back up, look for a GoTo mount that has a GPS system. An onboard GPS will allow for much quicker alignment. 

Are the components well-made?

  • With computerized telescope mounts, precision is absolutely essential to proper functionality. 
  • Any GoTo mounts that are made with cheap components will produce unexpected results, require continuous alignment, or not work at all. 
  • Because of this, you should always read reviews, recommendations, and anything else you can find about the mount itself—make sure it performs how it’s supposed to before you buy it!
