KOWA presents the most compact model of its range of telescopes along with the TSN-550 fluorite models, both available in bent and straight versions. The TSN-500 series are the entry range of the reputed ground-based telescopes KOWA.
The KOWA telescope TSN-501 has a 45-degree eyepiece that has a variable zoom of 20 to 40 magnifications and a target diameter of 50 mm. It has a minimum focusing distance of only 2.5 meters that will allow us to make observations of insects in exceptional detail. The body of the telescope is constructed of polycarbonate to make it robust and lightweight. It is water resistant and filled with nitrogen to prevent the lenses from fogging when there are sudden changes in temperature.

It is an ideal telescope for the initiation in the observation both for its low weight and size and for its excellent value for money. One detail is enough to know how good the product is: 10 years warranty. Enjoy it!
