I am selling three Carl Zeiss Huygens eyepieces. I have the 16mm, 25mm with .965" barrels and the 40mm screw mount model. All are in excellent optical and cosmetic condition. Each includes a nice plastic storage case.
The 40mm is $110, the 16mm and 25mm are $70 each. Free shipping if you by the set.
