Smart Astronomy LER 12.5mm
This is an excellent long eye relief (LER) eyepiece. It is the same as the William Optics SPL and Orion Edge On 12.5mm that sell for $149 at Andrews and Bintel respectively.
Eye relief is 20mm and AFOV is 55º. It's sharp across the whole FOV in all my scopes. Contrast and transmission are very good.
Selling because I have too many eyepieces in similar focal lengths.
Asking $50 plus post.
Enquiries by PM please.
