80mm Triplet Refractor Unknown Brand

Hello! Here I have an unknown brand 80mm triplet refractor. I got this for the mount it came on. Very solid scope. Well built. Not sure of the focal length because it comes with a threaded extension tube, but comes into sharp focus as pictured. I guess the extra tube is for binoviewers? Not sure. This is painted white but I wrapped it in carbon fiber. This has a 2in rotating 10:1 TS branded focuser that works, but isn't perfect. It's smooth, but sometimes there is a slight grinding feel to it at certain points. But does the job. Comes with sliding dew shield, 2in to 1.25in adapter, and tube rings with short vixen dovetail. Clean cemented optics. Will work with you on the shipping. Clear skies!
