With its easy portability and a sharp, aberration-free image, the straight-viewing TSN-66S 66mm PROMINAR Spotting Scope from Kowa is built for nature observation in the wild. A separately sold eyepiece is required for use.
scope's fully sealed, nitrogen-purged housing is made of durable but
lightweight magnesium, keeping its weight down to just 2.5 pounds.
Kowa's pure fluorite crystal objective lens all but eliminates fringing
for color accuracy and clarity, and the dual fast/fine focus makes it
easy to dial in the details of your subject. The tripod mount has two
holes with adapters that accept both 1/4" and 3/8" posts. A detachable
aiming sight on the accessory collar and another, built-in sight on the
sunshade help orient the scope toward the subject. The threaded collar
with bayonet mount accepts a wide range of accessories, eyepieces,
camera adapter for digiscoping, extenders, and more.
