From Manufacturer
Remarkably small and lightweight, the TSN-55 PROMINAR Spotting Scope from Kowa offers the same sharp, aberration-free viewing experience as its larger siblings in a highly compact package. The 10.8" scope comes with Kowa's TE-11WZ II eyepiece built into the body, with a magnification range of 17-40x, and its pure fluorite crystal objective lens all but eliminates fringing for color accuracy and clarity. Dual fast/fine focus makes it easy to dial in the details of your subject. Designed and manufactured in Japan, the scope is fully sealed and nitrogen-purged to prevent internal fogging from abrupt temperature changes. It comes with a pull-out sunshade, a 58mm filter thread, and an eyepiece thread for attachments including digiscoping adapters.
