I would rather sell these as a lot than individually so I'll try that first -- or trade for Parks Gold 30mm or Orion Ultrascopic 30mm or Celestron Ultima 30mm eyepiece in excellent condition with caps and eyeguard.
1. Touring the Universe through Binoculars by Philip Harrington (1990 edition)-- book in almost new condition; never read; front page (no text on that page) previously dog earred on upper right corner so can see a crease and minor rubbing to softcover
2. Exploring the Night Sky with Binocular by Patrick Moore (third edition, 1996) -- like new softcover
3. Binocular Astronomy by Crossen & Tirion -- hardcover; like new condition; 1992, first edition
4. Exploring the Moon through Binoculars by Ernest H. Cherrington (hardcover, 1969) - some wear to dj with clear Bodart plastic cover; cover taped to inside covers of book; clipped upper right corner of front two pages (no text on those pages); book itself is otherwise in like new unread condition
Cost for all four books including FedEx ground shipping within CONUS is $65; prefer money order or Paypal (I'll pick up the 3% for the use of Paypal)
