Siebert Observatory Series 36mm 2” eyepiece

This Is a nifty and very lightweight eyepiece made by Harry Siebert. It's an extra unit I'm selling because I already have a pair of these I use for binoviewing with one of Harry's 2 inch binoviewers. It's wonderful for widefield viewing and weighs just 9.25 ounces, despite having a 70° apparent field of view. Harry no longer makes these in a 36mm focal length, but he does make them in 35mm focal lengths and sells those new for $399 each.  This eyepiece I'm selling is in excellent condition and very clean. It comes with top and bottom caps. Offering this for sale in the US only, with the buyer paying shipping and any PayPal fees. Thanks for looking.
