Best Reflector Telescopes with Reviews

Reflector telescopes are a small category of the wide myriad of telescope types. Its differentiating factor is that they use one or several curved mirrors to reflect light facilitating image formation.

Reflector telescopes were incepted as an alternative to refracting telescopes in the early 17th century. Determining what is the best reflector or refractor telescope hugely depends on individual scope features.

Reflector telescopes are designed to allow a large objective diameter. Due to this, they are the major telescope type used in astronomy. These telescopes come in varying designs employing different optical elements all aiming at achieving an improved image quality. (more…)

What is a Catadioptric Telescope?

Telescopes are essential devices for any aspiring astronomy enthusiasts. Just to mention, telescopes make it easy to see far objects. Due to their varied use, telescopes come in varying designs, each best for a specific function. Broadly, telescopes can be classified as professional, amateur or commercial types. However, they can also be grouped based on optical design or mechanical design. The other minor classification is based on where they are placed, for instance, space telescopes.

That said, catadioptric telescopes fall into the group of optical telescopes. Also called compound telescopes, they are hybrid scopes which combine lenses and shaped mirrors to form an image of the object. These telescopes combine the best features of reflectors and refractors in one package.

Due to this, they have a greater degree of error correction compared to other lens or mirror counterparts. They also have a wider field of view for an excellent view. (more…)
