Best Catadioptric Telescopes - With 100 to 150 mm (Aperture)

The main considerations when selecting a telescope are the aperture level and focal length. A larger aperture enables one to see far objects with less light. However, the bigger the aperture, the bigger the telescope, which limits its portability. The focal length impacts the viewing distance. Another important consideration is the type of telescope (reflector, refractor, or catadioptric), which determines whether it is compatible for close and bright objects (as the moon) or for long-distance stars.

Catadioptrics are the most popular telescopes for deep-sky and bright objects stargazing. A compromise between a reflector and a refractor telescope, they offer the best features of both. They are good for astrophotography, and most models are compact and portable. Their price normally falls between reflectors and refractors.

Telescopes with an aperture of 100-150mm (4-6 inches) are great for seeing plenty of deep-sky objects. With 150mm aperture, you will see Saturn’s Rings detached from the planet ball, as well as galaxies beyond our Milky Way. An aperture of 100-150mm is a good starting point for serious beginners to gain stargazing experience.
