Telescopes for Deep Space – Buying Guide & Comparison


Because time is of the essence, you may want to find the best telescope for deep space objects without spending too much time. We hope that his short paragraph should aid you to get the model you need. After a careful analysis of the market, we believe the SkyWatcher S11610 to be the best because it offers a large 8’’ aperture that due to the amount of light it draws, allows detailed viewing of the moon and nearby planets. The straightforward design of the product makes assembly an easy task, as everything is designed to go together perfectly. The base weighs in at 25 pounds which provide a steady platform with close to no vibrations, making it extremely easy for you to observe celestial bodies without any interference from the device. If by any unfortunate event the SkyWatcher S11610 is unavailable for purchase, we recommend the Orion 8946 as your second purchase.

The Good
The Bad



Finding the best telescope for deep space can be a strenuous task, especially as it demands a deep understanding of technical terms and features that can leave you more confused than ever. With the many options available for sale, settling for just one can be close to impossible, especially if you lack time to explore the market properly.

If you take the time to read our buyer’s guide, we believe that it will help simplify your decision-making process, by providing you with all the information you need to make a learned choice.

The Aperture

The first thing you have to bear in mind when buying a telescope is the size of the aperture. This is one of the most important features as it dictates just how clear and detailed the image that you view through the lenses of your device will be.  

To describe it in simple terms, the aperture is the hole or opening through which light travels. The larger the aperture, the more light you will get. The more light you get, the easier it will be for you to notice faint deep space objects that don’t emit much light.

The common consensus among experts is the larger the aperture, the better the telescope. It also has to do with what you expect from the product if you want detailed imagery of long distance objects you can’t go wrong by going for a large aperture.

If you want to have a better grasp of how the aperture of a telescope fairs compared to that of the human eye, we believe the following comparison will be quite telling.  An aperture of 8’’ can capture 816 times more light than the human eye. The further you look away from the sun, the more devoid of light the objects and planets will be, this is why a good telescope for deep space needs a large aperture.


The Focal Length

Though not as important as the aperture, the focal length is one detail that you should still pay close attention to. Just as with the case of the aperture, a bigger focal length is more beneficial. Greater length will make the objects that you’re viewing look larger than they would with a smaller focal length.

You also have to consider that the size of the focal length will influence the size of the product, the bigger the focal length, the larger your device will be. You should have this in mind, especially if size is a major factor to you and you require something more compact.

We recommend to go for an alternative that offers the biggest focal length, but if you find yourself having to choose between a big aperture and a big focal length, we advise to go for the former. The same thing is true if you want to a compact telescope, we recommend going for what is more practical to you.



If you are considering buying a telescope for the first time, you could have been led to believe that magnification is the most important feature to have. While this is still true, a high level of magnification is useless if you don’t have lenses that can give you a clear image.

The good thing about magnification is that almost all telescopes allow you to change the eyepiece. The eyepiece is the lens you look through with your eyes. You can change the eyepiece and go for one that offers you a higher or lower level of magnification, depending on your needs.
