FS: 100mm f/10 Showa fluorite refractor, like new condition.
Although not well known in this country, Showa is respected in Japan for its observatory-class instruments. This one lives up to the company's reputation, with sharp, contrasty images. A Zygo test report is included (from Mike Palermiti) showing a Strehl ratio of 0.98. It's an excellent lunar/planetary scope that also does a nice job on deep-sky objects.
In addition to the OTA, there are a nice 50mm finder, a 1.25"/2" adaptor, and Parallax rings.
Reduced price is $1590 + shipping.
