Astronomical telescopes – Buying guide & Comparison


If you’re short on time and you just want to find the best astronomical telescope, this short paragraph should help you get exactly the model you need. According to our research, the Orion AstroVIew 120ST is the best model for sale because it comes with a 120mm aperture that is ideal for viewing deep space objects and when it is combined with the long focal length celestial bodies appear sharp and clear. Since it comes with an equatorial mount you can easily track objects in the night sky, and the Starry Night software ensures you know exactly what you are viewing. If the Orion AstroView is not available, your second option should be the Celestron NexStar 6 SE.

The Good
The Bad



Whether you are just getting interested in astronomy or are already familiar with the various stars and planets, it is important to have the right telescope. There are several types to choose from and unless you know exactly what you need, making the right decision can seem overwhelming. In this buying guide we have included informative tips that will make it a little easier for you to pick the best stargazing telescope.  


Aperture and Magnification

According to the best astronomical telescope reviews one of the most important features to consider is the size of the aperture. This will determine how bright and sharp your view is, and whether you can see deep space objects or only those closer to Earth. Larger apertures gather more light and allow for more magnification. This is usually done by changing out the eyepieces. If there isn’t enough light gathered, even using a high magnification will be pointless since distant objects will still appear faint and blurry. Most experienced astronomers agree that it is always best to pick a telescope with the largest aperture your budget will comfortably allow.


Types of Mounts

The mount on a telescope is often overlooked by beginners, and this is a mistake. Even a telescope with the best optics will be basically useless if it comes with a cheaply constructed mount. In order to track celestial and even terrestrial objects the mount needs to be sturdy, stable and able to work smoothly. There are a few types of mounts to choose from, and each comes with its own advantages.

The best astronomy telescope for beginners often comes with an equatorial mount. They can easily be motorized, and this is always a benefit for astronomers just starting out. These mounts are also considered the easiest to operate operate since you can track objects using only one axis. Altazimuth mounts are lighter in weight, but are considered to be a little harder to operate. It is also more difficult to motorize these mounts, and this can affect the performance of the telescope. There are also Dobsonian mounts which are incredibly easy to set up, lightweight, and typically priced to fit almost any astronomer’s budget.


Telescope accessories

Telescopes can come with a surprising array of accessories and some can dramatically improve your experience. Models that come with one or more eyepieces allow you to view objects up close and at a distance. Some telescopes also come with a Barlow lens which can provide you with extra magnification. Finders are a convenient extra that beginners should carefully consider since it makes it a little easier to locate an object in the night sky. Included tripods are always a convenient extra, and provide a stable base. Beginners and experienced astronomers will also appreciate models that come with software or provide access to an information database. This way you will always know exactly what you are viewing.
