This Celestron 20mm Kellner Crosshair eyepiece is in like new condition and includes barrell caps and the original box. It's great for aligning your finderscope, digital setting circles or "go-to" scope. I'd like $20 which includes insured shipping to your door in the CONUS. Money order, cashier's check and PayPal(if you pay the 3% fee) are all o.k. Thanks for looking.
