This is actually a vixen 60mm f5 short tube refractor. I have added rings to it and used it as finder on my 13.1 coulter. The optics are in excellent condition. It comes with the ota, the vixen diagonal(.965), 2 extension tubes, a set of rings, a 32mm B&L plossl, and mounting hardware. The extension tubes are used depending on which eyepiece you use(the eyepieces are interchangeable).With the supplied eyepiece I believe you have a 5.33 degree field of view. I am selling to fund the purchase of a larger dob. Asking $100 shipped. Please feel free to ask any questions.
