  • 55mm fluorite crystal objective

The Kowa TSN-55S Prominar is the straight version of Kowa's 55mm travel scope. It comes with a 17-40x zoom eyepiece and weighs 960g, so it is easy to carry on long walks and trips abroad.

Fluorite crystal in a travel size

The 55mm objective is fluorite crystal, which keeps colour fringing very low. The supplied 17-40x zoom eyepiece is designed for this scope.

Made to travel

The body is waterproof and nitrogen filled, and at under a kilo it fits in a daypack or carry-on bag.

Why choose the straight version?

A straight scope points where you look, so it is quicker to find a bird, easier to use from a car window or a hide, and simpler for beginners.

The TSN-55S in numbers

The TSN-55S has a 55mm objective, a close focus of 2.8m and a 58mm filter thread. The body weighs 960g.

Which Kowa scope should you choose?

If this isn't quite right, the TSN-55A is the angled version; the TSN-66 kit gives a 66mm objective and 25-60x zoom.

Filter thread: 58mm
Length: 275mm
Magnification: 17-40x
Minimum Focusing Distance: 2.8m
Objective Lens Effective Diameter: 55mm
Objective Lens Material: Fluorite Crystal
Weight (Body): 960g

How close can it focus?

Down to 2.8m.

How much does it weigh?
