Kowa Millenium TSN-821
82mm

Tested in 2000 trials for
BirdWatcher's Digest

by Michael and Diane Porter

Kowa 82mm scope

Kowa Prominar TSN-823

In Kowa's TSN-823 Prominar, they went for a slightly oversized objective lens of 82mm, thus increasing light transmission by 13% over their old 77mm scopes.

The scope has a peep sight on its right side and a pullout sunshade. It's well sealed, nitrogen purged, and waterproof, with a high-impact polycarbonate body. A hard screw-on lens cap protects the whole eyepiece assembly with a rigid plastic cap. The lens cap screws on also, so the scope is suitable for carrying around.

Our judges deemed it on the large and heavy side. Maybe full-bodied is the word for it, with its large prism housing. However, the optical quality is excellent, and it is a good scope for the price.

The 20-60x zoom eyepiece has good eye relief for glasses wearers, at least at 20x. It is not so usable at higher magnification.
