Vixen Lanthanum 5mm Eyepiece. Bought 2 months ago. Barely used. Getting rid of becuase I was given a radian eyepiece as a gift and I don't need the eyepiece anymore. Orig. Box.
These Vixen brand eyepieces (6 to 8 elements) are a new breed, using the rare earth glass lanthanum in one of their field lenses, for almost total freedom from any visual aberrations. The focal length has a comfortable 20mm of eye relief. The eyepiece also feature soft rubber eyecup, rubber coated body, and fully multicoated lens for optical excellence. Asking $75 Shipped.
