Koah Perihelion Professional 5' Lightweight Aluminum Camera Tripod with 360-Degree Ball Head

Lightweight, portable and sleek, the Koah Perihelion Professional 5' Tripod is a reliable accessory for the modern photographer. Just like its predecessor, the Aphelion, the Perihelion features a 360-degree ball head that helps capture beautiful panoramas. And it inverts and folds for easy carrying on the go.

Increased Stability

With a load capacity of 33 pounds, the Koah Perihelion Professional 5' Tripod provides security and stability for your DSLR, mirrorless or smartphone camera. An attached hook lowers the center of gravity for increased stability. The Koah Perihelion tripod is built with a lightweight, tough and reliable aluminum alloy for extra strength and durability.

Compact and Flexible

The tripod can be extended up to 5 feet tall or collapsed to just 17 inches. The twist-lock legs invert and can be folded back 180 degrees, allowing easy carrying and storage. The center axis can also be inverted, allowing excellent macro photography. The metal ball head can be rotated 360 degrees, helping to expand camera activity range for panoramic shooting. The bubble level helps with judgment and accurate composition.

Detachable Monopod

Turn this Koah pro tripod into a monopod or walking stick to make your photography more diverse. The monopod satisfies your needs during high-angle tilt shooting and low-angle shooting.

Kowa Sporting Optics 15-45x55 PROMINAR Pure Fluorite Straight Spotting Scope

The TSN-554 15-45x is a unique compact spotting scope featuring a fluorite crystal objective lens, designed to make your journeys truly memorable and immersive.


At the heart of the TSN-550 PROMINAR series spotting scope beats a fluorite crystal objective lens.

Fluorite crystal is a unique feature of Kowa spotting scopes and is a testament to decades of Kowa optical developments. Measuring just a mere 288mm in length and weighing only 800g, this spotting scope is truly compact and makes the perfect travel companion.


This spotting scope represents a way of thinking, a way of life. An optic that enhances every moment you use it. It’s unique. A spotting scope this compact creates new opportunities. Wherever your journey takes you, the Kowa spotting scope is the perfect travel companion. A lightweight yet durable, fully waterproof and nitrogen-filled chassis ensures performance in the toughest of environments.
