This is a wide angle (aprox 62deg apparent field) lens
cell assembly from wide angle 7x35 binoculars mounted in a
machined aluminium 1.25 barrel for astronomical use. Eyepiece
is wide angle kellner type and features coated optics and removable
rubber eyeguard. Focal length is about 22mm. I have a set of wide
angle University Konigs and field is about the same as is optical
performance. Only asking 15 bucks shipped in USA. Check or MO.
