Vixen-made Orion Lanthanum Superwide 3.5mm. Bought new by me about two months ago. 65 degree apparent field of view, 20mm eye relief. Like new in box (has been in a focuser just a few times, so there are just a few scuffs on the chrome barrel, otherwise it's perfect). New from Orion they're $229 + shipping. I have no idea why the used market discounts these so much, but I give up. I'm using a 7mm Nagler T6 with a Tele Vue 2x Barlow now, and I need a new lawn mower more than this eyepiece.
$165 shipped in US. SALE PENDING (Thanks, Carlos)
