Types and Mounts

While there are several models of telescopes already on the market, if you travel a lot or if you simply prefer to have the freedom of choosing your stargazing locations, instead of viewing the sky from your room and balcony, then a portable telescope is what you’re searching for. Easy to carry, but packing a powerful and high-quality image, let’s take a look at what types you can choose from.

• Refractor – standard, durable and the most common type. It gathers environmental light from one end and focuses it into the eyepiece at the other side. While it is true that it regained its popularity thanks to the fluorite, and despite the fact that it can offer high-quality images, it does tend to be susceptible to chromatic aberration.
• Newtonian reflector – named after the well-known scientist, it uses a parabolic mirror to focus light from the front end to the eyepiece at the back. It doesn’t suffer from chromatic aberration, but it does require constant collimation, as it tends to defocus quite easily. Additionally, you have to be careful not to use it on cold days, as the mirrors inside it can cloud up.
• Schmidt-Cassegrain – commonly known as SCTs, it tends to be quite compact. It uses a mirror at both ends to fold the optical path, thus making it a more compact version to its counterparts. It tends to come with a variety of accessories, but its image quality cannot reach its counterparts.
• Catadioptric – also known as compound telescopes, they are a hybrid between a reflecting and refractor one. With an overall shorter length, they are portable and are capable of avoiding the aberrations the other versions tend to not escape from. While they might seem better at first glance, they are quite pricey and they do require calibration from time to time.

Aside from the lenses, the mount is an essential part of your stargazing experience, as well. There are two types of mounts that, according to what you need it for, will definitely fit your requirements:

• Equatorial – it is designed to follow the rotation of the sky. A bit on the pricey side, it will make, however, your ‘starry’ experience a lot more immersive and will be able to help you track the celestial bodies, easier.
• Altazimuth – it can be considered more like a standard mount. It can move up, down, left and right, but it will not automatically track the sky, so it will need manual adjustment. However, it is more affordable and more compact, thus it packs lighter than its counterpart.

So, it all depends on what you’re looking for and how much your budget can stretch. While an expensive one can be exactly what you’ve been searching for, a more modest version can easily offer you a high-quality for your stargazing moments, as well.
