How it Functions

The telescope must be assembled first before it can be used. The basics of a how a fully assembled 127EQ PowerSeeker telescope works is described below.

The telescope is first directed to the object of focus in the night sky. The light from this object then travels into the telescope, where the light rays strike the primary convex lens, which bends and refracts the light rays thus focusing the light onto the secondary lens. The primary lens is described as the objective lens. The second lens is the secondary lens, and is also called the focusing lens because it focuses the lights rays from the primary lens, before allowing it to reach the eye of the observer. This way, the observer can get a sharp and clear image of the object being viewed.
