I have a mint condition
12mm BST Explorer for sale. Bought a few months ago. Comes with caps and box.
Has a 60° AFOV and good eye relief. The eyecup screws up and down like Pentax eps. Performance is surprisingly good. On star fields I like it better than my Pentax XF
12mm as it has a flat field.
Selling because I have too many eyepieces in similar focal lengths.
Unlike the
12mm Paradigm/Starguider models, the
BST has
blue accents on the body, not red (this was disappointing cos I wanted it to match my red SV66ED!

)
Asking $75 ono.
Enquiries by PM please.
