The Good
The Bad



If you’re on the hunt for a good monocular for stargazing and you can’t seem to find one that best suits your needs, the first thing you have to do is take a step back and understand that the models designed specifically for astronomy are different from typical ones. Also, there are other aspects you must consider to be able to make the right choice.

For more information, we suggest reading the guide we’ve put together below. Over time, we’ve published many other articles, and the topics of these range from binocular accessories to how you can get the most of your brand new monocular scope.


Magnification and size of the objective lens

They say bigger is better in most cases, and this is especially true when it comes to stargazing monoculars. You want your model to come with the largest aperture possible, and the magnification has to be the most powerful, too.

But the problem that comes from buying the so-called best model in this sense is that it will end up being bulky. Just as you would when getting a telescope or a pair of binoculars for the same purpose, you have to consider the way you’re going to use your monocular.

Naturally, amateur astronomers should try to look at the sky while they’re out of town because if you do this from your balcony, the image will be affected by light pollution and will effectively prevent you from seeing any celestial object.

On the other hand, the smaller and the lighter the monocular, the less likely is it for it to be expensive. In the end, you must make a trade-off between specs and cost, since higher priced alternatives usually come with a more powerful magnification and a big aperture.


Optical quality

Faint celestial objects and stars are a lot more demanding compared to daytime scenes, and so you don’t want the optics of the instrument you’re purchasing to be mediocre. You wouldn’t believe the number of flaws you can discover when you look at the sky, especially if the product you have chosen doesn’t come with high-quality optics.

Price is a relatively good indicator of the quality of the lenses. No decent unit will be a cheap monocular for stargazing. Choose fully multi-coated optics for the best results.


Stability and image shakiness

If you are planning to use your monocular without any stabilization system, we hate to disappoint you, but it might not meet your requirements. The higher the magnification and the bigger the objective lens, the heavier will the unit be.

That means that your hands are going to be shaky and so, in turn, will be the image. Use a tripod or a monopod if you want to get a model that’s not exactly lightweight. Keep in mind that a bigger objective lens diameter will allow the optical instrument to capture more light, so the image will be brighter and you’ll actually be able to tell what celestial object you are looking at.
