I have moved to the 2nd Edition of Uranometria so these have been taking up space in my observatory library. They need to be used. These are from the 1989 printing. The acetate overlays are still in the back cover and have never been used. While I have used these in the field I took very good care of them. I would rate them as an 8 out of 10. I'll sell the pair of them for $55 including shipping in CONUS. I'll take a personal check (wait for clearing), a money order or PayPal plus 3%. Thanks.
