I bought sets of these eyepieces and I'm keeping one and selling the others. They are .935", and fit a .965" to 1.25" adapter if you wrap a few turns of electrical tape around the barrel. These are excellent, with only a few minor marks on barrels. Prices are shippped Priority Mail in CONUS. Buy BOTH for $60 shipped!
Leitz Wetzlar Periplan 10x/18 (eyeglass symbol): This is a nice 25 mm lens with a FOV just slightly smaller than a TV Plossl. Sharp to edge, field stop is 18 mm, eye lens about 18 mm. $35
Wild Heerbrugg 15xW: This is a 16.67mm (call it 17mm) e.p. with approximately 60 degree field of view, sharp about 2/3 across the field. Field stop about 18 mm, eye lens a bit wider, fairly heavy for its size and multiple elements. Good eye relief. $35
Money refunded (minus shipping) if you don't like 'em - but I think you will. Thanks for looking.
