This is the 1st edition Uranometria 2000 star atlas (reprinted June 1989), volume 1 (Northern Hemisphere) and volume 2 (Southern Hemisphere). They are in absolute mint condition, and have never been taken out in the field. I've actually just "peeked at" the pages since I bought them new. The acetate overlays are included. $60 for the set shipped to you, Paypal or MO.
