Current model Astro-Physics 2" Convertible Photo-Visual Barlow (Barcon). As new condition. I simply do not use this outstanding barlow and it has been sitting in its case untouched for too long. I am the original owner and the Barcon comes in its original box with top and bottom end caps packed exactly as received from AP when new.
This is a 2 piece barlow that can be used in various configurations and it produces 2x when used before a diagonal and 1.7x used after a diagonal or camera adapter.
AP or Anacortes retail price $210. Sale price $170 shipped Priority Mail in US. Paypal accepted but please add $5 to cover the 3% charge to me.
Thanks for looking!
