Best Reflector Telescopes - With Up to 100 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 100mm (4 inches) or less are for beginners who want a small size telescope for stargazing (a minimum of 70mm aperture is suggested). For observing galaxies beyond our Milky Way, you will have to be in dark locations. You may see Saturn’s Rings but not separated from the planet ball.
