I still have 2 Zeiss eyepieces left:
16mm ortho. older design, no engraving around rim, 16-O engraved on top. Glass clean, no scratches rest good used condition.
25mm huygens, nearly new, glass clean, no scratches, Carl Zeiss Jena engraved around rim, 25-H on barrel. really nice, surprising views for a Huygens, great for solar projection as well. $70 shipped
Zeiss Sonneglass solar eyepiece filter, neat collectable but DO NOT USE IT !! Black glass filter scews on in place of eyepiece ring. mint except for burned spot inside glass (yikes!!) $30 shipped
