I have a C-90 Celestron Spotting/Space scope in Mint condition from the Mid 70's when they were made right. Has multiple eye pieces (Schmitt Cassegrain). Has been stored in its padded hard case in my residence all these years. I even used it to see Hallys Comet. Very high quality. $275 Delivered. OR Would love to trade for a nice rifle scope in the league of 3x9's such as Nikon, Burris, Leupold, etc. Pictures on request.
