Bought the set of three, keeping the 26mm and 40mm, selling the 32mm. Four elements, fully coated. Field stop diameter - 36.5mm. Apparent field of view - 65 degrees. Weight - 12 ounces. Eye relief - 22mm. Comes with bottom cap but not top (None of them did.) Very nice eyepiece ... certainly usable at F/5, but I'd recommend F/6 or slower scope. $60 shipped/insured Priority Mail. Thanks for looking.
