Kowa Prominar TSN-4 Exceptional Spotting Telescope Portable Scope Flourite Lens

Thanks for looking at this factory original Kowa Prominar Telescope / Spotting Scope with 77-30X Wide Eyepiece. This is an awesome piece of equipment that has been incredible over the years. There is an example of what the birding community thinks of it on Birdforum but I cannot include links here.

Optics on this piece are still close to perfect. Really good optical condition, fair to poor aesthetic condition. Tripod base and ring around scope are slightly loose and I would suggest replacing / tightening them.

This is a well-used scope that has spent time in Africa, Central and South America, Europe, Asia, and the Middle East. I have watched Eland with it in South Africa and Godwits in California. My father was its original owner and used it heavily, including dropping it once on rocky ground. The scope works perfectly but is dented and has scuffs, a few scratches, and signs of wear. I eventually upgraded to a newer and angled Swarovski but kept this around.

Says Kowa: The TSN 3 and 4 PROMINAR models incorporated pure fluorite crystal objective lenses which delivered the brightest, sharpest, and clearest images compared to any other spotting scopes. Even though fluorite is an ideal lens type which has extremely low chromatic aberration (color fringing that appears on the periphery of the images), it is crystal instead of glass and is more difficult to process and polish and is, therefore, more expensive. However, fluorite lenses had to be used to deliver "the world's best viewing characteristics". The TSN 3 and 4 models were the first to have PROMINAR printed on the scope body which had previously been used only as a descriptive name. An awesome item at a fantastic price!
