32-mm Wide Field Eyepiece $95 incl. Postage in USA Sold!
This an old eyepiecea six element Erfle contains rare earth glasses and works very well with short focus telescopes yielding extremely wide fields. Originally used with a five inch F/5 refractor which I traded, but the eyepiece was never remounted. With long focus it similarly yields wide views; for example at 4000-mm you can see the entire moon and Sun are spectacular at 125X.

Eye lens is 47-mm diameter. (1.85 in)
Diameter at base of eyepiece is 65-mm (2.56 in).
This eyepiece can be easily adapted to a large (2.7in or larger) focuser.
It’s in very good condition; considering its age it’s in excellent condition. There are no scratches on the glass and it is coated. It weighs about a pound.
