Well made OCA for dobs and refractors (this model #1a on his website). In practically brand new condition. Will only increase power by 1.25x, which is great for binoviewing with multiple eyepiece pairs because it allows the use of so many higher powered focal lengths. Includes dust caps and bolt case. $100 shipped ConUS.


  • Condition New
  • Location Lillington, NC
