An affordable and high-quality option for your first telescope! We recommend the Velbo Videomate 638 aluminum tripod with video head as a companion. The video head allows for smooth subject tracking.
This set includes a Kowa TSN-501 body and a Kowa 20-40x zoom eyepiece. The eyepiece is fixed to the telescope and cannot be replaced.
The Kowa TSN-501 terrestrial telescope is a lighter and more affordable version of the Kowa TSN-553 Prominar telescope in terms of features. The front lens of the TSN-501 telescope is slightly smaller than its big brother, and the front lens is not made of fluorite crystal. The optical accuracy is not as good as the TSN-553, but it is still a very high-quality telescope in its price range. This is an excellent option for a first telescope
Kowa's goal has been to develop a compact telescope that, despite its small size, would compete with the best on the market. Kowa has now succeeded in this goal with the launch of its compact and lightweight TSN-501 telescope. Weighing only 400 grams, the telescope has a focusing distance of only 2.5 meters, making it suitable for observing small and close objects, such as butterflies.
The telescope is nitrogen-filled (IPX6), making it waterproof and preventing moisture from condensing between the lenses. The front lens coating repels dirt, grease and water, making it easy to keep the lens clean.
