This is an iOptron 2" 30 mm Super-View Fully Multicoated Eyepiece. This eyepiece has an apparent field of view (FOV) of 68° and a comfortable eye relief. It can be used with any of the iOptron telescopes or astrographs, provided they are designed to accept a 2" eyepiece barrel.

This eyepiece has a precision machined aluminum barrel and a flexible rubber eyecup to help block stray light when observing. It has a 2" OD barrel and therefore it requires a telescope with a barrel designed to accept 2" eyepieces.
