A 10' Buchroeder Tri-Schiefspiegler optics set- I purchased these optics from Dr. Buchroader many years ago. This is a 10" primary with two 4 1/4" secondary mirrors. The coating are in very good condition. The mirrors were made by Jacobson of Puyollup , Washington. I also have the homemade wood mirror cells which came with the mirrors and have built a plywood tube which would have to picked up( No shipping on the tube.)Buyer pays shipping and handling and insurance. Paypal or M.O. ASAP after the deal is closed. WILL SHIP MIRROR AND CELLS ONLY, TUBE PICK UP ONLY. $750 firm on the optics and $50 for cells. These optics deserve some nice open sky.
