Borg 100mm Achromat. Optics and focuser in excellent condition; outside of tube shows some wear (scratches/digs from mounting), but not bad. Includes Borg tube rings, Orion soft padded carrying case. This is a very nice, sharp, lightweight 4" refractor (see reviews on cloudynights). $600 shipped in CONUS. Let me know if you have any questions. Thanks!
