From Wikipedia: "A refracting or refractor telescope is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long focus camera lenses."

This small handheld telescope is for scouting out new frontiers, whether trudging through the jungles of the Dark Continent or the Venusian wilderness.  It weighs in at 184 faces, or 336 triangles, and has only procedural textures.  A simple armature allows it to extend or retract, as well as tilt.

Hint: Try swapping around some of the materials, or appending some from my materials library, to achieve a different look.
