In-game description
"While the physics behind a telescope have been well-known for some time, the glass-grinding skills required to actually construct one are still quite specialized. The lenses of this telescope are finely made, however, and its collapsible tubing has obviously been wrought by someone well-versed in the delicate art of jewel-setting and metalwork."
