What Is the 565 Refractor Telescope?

Definition

• A refractor telescope is a kind of optical telescope that uses a lens, rather than a mirror, to gather and focus light from the visible part of the electromagnetic spectrum. The refractor telescope uses this light in order to display view a magnified image of distant objects.

Operation

• The 565 refractor telescope bends, or refracts light. This refraction results in parallel light rays converging at one focal point. The light rays that are not parallel converge instead upon a focal plane, or plane that is perpendicular to the axis of the lens. The telescope divides parallel rays into two bundles and converts them into angles. The ratio of the angles is referred to as the angular magnification.

Telescope Specs

• The 565 refractor telescope has a focal strength of 705 mm. The telescope also contains three eyepieces, sized 8 mm, 12.5 mm and 20 mm. Magnification ranges begin at 38, but can increase up to 565. The telescope also includes an equatorial mount and a finderscope, or small auxiliary telescope that mounts on the main telescope, for tracking purposes.
