Price drop: Celestron Ultima 12.5mm
This is a five-element 'pseudo-Masuyama' eyepiece that offers better correction and more eye relief than a Plossl.
Condition is very good. There is, however, a small black mark at the edge of the field of view. It seems that some part of the baffling or something is intruding slightly into the light path. I only notice it when looking at the moon.
Reduced to $60.
Enquiries by PM please.
