Selling a 10cm f/10 Showa fluorite doublet refractor in excellent condition. I've used it mainly to get beautiful views of the Moon and planets but double stars and clusters are also pleasing and sharp. Even my wife, who humors me by looking through an eyepiece once in a while, commented how sharp the images were. A Zygo test report (included) shows a Strehl ratio of .98.
Rings are included, as are a nice 50mm finder with good eye relief for glasses and both 2" and 1.25" adaptors. The OTA weighs about 12 pounds (5.4 kg) and is 42" (107 cm) long. I use it successfully with a Tak EM-2 mount, which is rated to about 15 pounds. I'd expect a GP-DX or similar mount to hold it very steadily.
I've bought a larger scope and, as much as I like this one, I just can't justify keeping it. For a photo, see Astromart ad #83652.
