Best Reflector 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.

Reflector telescopes are cheaper entry-level choices for deep sky objects (with low light). They are more portable than refractors and the only type of telescope that does not show a mirror image (helps in sky navigation). Reflectors require more maintenance (cleaning away dust and aligning mirrors).

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.
