Orion Collimating Eyepiece
Here is my Orion Collimating Eyepiece for Newtonian telescopes. Last used a few years ago.
Given it's a passive accessory with no fiddly bits, I'm not sure what to say other than it's in great condition and undamaged?
Asking price: $28 shipped in Oz.
(Not posted under Eyepieces as it's not used for actual astronomical viewing)
