It was only last year that Kowa pulled off a major coup with the launch of the TD-1, the world’s first telescope to include a built-in digital camera. Prior to this, the company had long been renowned for its production of high quality telescopes, which continue to retain a significant element of popularity among birders throughout the world. One of these models, the TSN-663 ED, has been on the market for two years, and I recently took it out for extensive testing in the field.
