They're easy to use, deliver sharp images and are modestly priced. You should consider them for viewing the moon, planets or stars that are relatively bright. Reflector models feature a side-mounted eyepiece and produce very bright images. They are lighter and more compact than refractor models. You can use them to view distant stars and galaxies that are relatively faint. Learn More: Focal Length Focal length is the distance from the lens or primary mirror to the focal point. For example, a telescope that has a 1,000 mm focal length features twice the power of a model that has a 500 mm focal length, but only half the field of view.
