Best Refractor Telescopes - Up to 900 mm (Focal Length)

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.

Refractor are for observing larger and brighter objects. They are the best choice for the moon and large planet stargazing. They are low maintenance, because the sealed tube prevents dust from entering. However, they can suffer from some chromatic aberrations (which is fixable), and they are generally more expensive and heavier.

Telescopes with a focal length of 900mm (35 inches) or less for looking at large objects and star fields. They are not suitable for small objects or for observing fine details on the moon.
