I received this 17mm nagler type 4 as a birthday present about 2 months ago. The family member that gave me this gorgous eyepiece did not relize that I already had one. I have never opened the box at all. It is brand new. This eyepiece has never seen a telescope. There are no dings or scratches on the eyepiece what so ever. I am asking $320 for the eyepiece. I am paying for the shipping charges. If there are any questions at all please feel free to ask. Thanks everyone.
