This scope has been sold under several names. It is an 80 mm f/5 achromat with excellent optics. Includes scope, 90 degree diagonal, 26mm plosal, and finder scope (no end caps for finder) The scope has a 1/4x20 tripod mount block on the bottom of the tube. I used this scope as a "finder" for a C14. It has very good optics, and I have used it for wide field CCD. There are some scratches on the tube, but otherwise it is in excellent optical and mechanical condition. Asking $125, shipping included. Paypal plus 3% OK.
