FS: Here's a monster lens cell with two lens 3 3/8" diameter for $15. The aluminum black anodized lens cell is 4.5" long and threaded on the outside on one end. The front lens is convex and the rear is flat. The lenses look to have an AR-coating. They need cleaning, but I see no flaws in the surfaces. The assembly has about a 12" focal length. I have no idea what this thing was made for, but it must of cost mucho dinero. Impress your friends, light your camp fire, or May be you could use it to make a giant eyepiece for an even gianter telescope? Ships medium priority flat rate box for $15, yes crazy, the same FS price. All dimensions are nominal.
