I have a somewhat unusual Zeiss 25mm Konig for sale. It has had the bottom 1/4 inch cut off to provide a wider FOV and has the field stop removed. I have the field stop and will ship with the eyepiece, but I have never used it as this eyepiece is sharp to the edge in my scope. I am also including a generic eyecup that I used in my light polluted yard. This eyepiece has the older orange tinted coatings (I believe MgF) but the optics are pure Zeiss.
$60 shipped to you, check, MO, non-credit card paypal, interesting trades, etc.
