Standard 1.25" barrel eyepiece from a special purpose telescope.
It looks like one of the Japanese orthos that Edmund used to sell,
but has no printing on it except "Or 25mm". Good quality, optics
are in beautiful shape. Chrome barrel has internal filter thread.
There is no field stop in the barrel; you can add one if desired.
Image quality is good. Barrel shows a little wear, upper black
part of body looks almost new.
Paypal instant fund transfer is the only payment method I can
accept for this item. Price includes First Class Mail shipping
in the continental US. Shipping address must be Paypal confirmed.
Other reasonable offers considered. Thanks for looking.
