What can I see with this telescope?
Max reasonable eyepiece power (no Barlow) in good seeing is approximately
— mm (—×)
Bright objects such as the Moon and planets may allow you to use approximately
— mm (—×)
Larger aperture (diameter) telescopes will produce a brighter view of objects
Viewing location and sky conditions can vary and will affect actual results.
