For Sale: Siebert Optics Binoviewer and matching eyepieces.
Henry Siebert binoviewer in excellent condition. Includes case, an optional leather cover, and eyepiece case. I am second owner. Originally new in 2001, and purchased by me in Dec 01.
Includes two shafts-- one with a 1.7x Barlow. Siebert customized this unit for the first owner. The Barlowed shaft on this one is threaded for 1.25" filters. The non-Barlowed shaft is the standard unit with the Siebert filter holder. Harry also added a custom set screw to the right hand eyepiece holder, which has a diopter adjustment. This prevents slippage once you have it adjusted where you want it.
Includes two Siebert 21mm eyepieces (80 degree apparent FOV). Package also includes matched Siebert eyepiece sets in 15mm, 10mm, 7mm. All have a 65 degree FOV. The 10mm and 15mm eyepieces have 7mm eye relief, while the 7mm eyepiece has 6mm relief. $500 plus actual shipping costs.
