I have a pair of Orion Ultrascopic eyepieces 25mm. These are best in a binoviewer but would also be good for widerfield viewing.
$130 the pair including postage to Australia.

Excellent condition, one cap missing.
For sale as I sold my Binoviewers and I already have an eyepiece in this focal length.
