1988 TeleVue 13mm original-style Nagler eyepiece. This eyepiece has seen lots of service so it is not in new condition. Cosmetically it shows lots of small marks on the barrel and the original setscrew has been replaced. There is also a very minor 2 mm slick on the eye lens. This does not impede optical performance and is only seen on the lens at certain angles. This is a big, heavy eyepiece with no rubber grip or eyeguard - that’s the way Al made them back then. Now the good news, this is a great deep-sky eyepiece. If you want the Nagler experience without the high price, this eyepiece will deliver. And some more good news, I’m selling this for $89 shipped to your door anywhere in the lower 48. Personal check is fine.
