7410 - Eyepiece Projection Adapter

The Borg eyepiece projection adapter (part number 7410) is a versatile solution for doing eyepiece (positive) projection or afocal photography with 35mm film, or digital still and video cameras. Solid construction complements a design that does not place the weight of the camera on the eyepiece itself.


An internal diameter of 54mm and an adjustable internal length (34-52 mm) accomodates an exceptionally wide variety of eyepieces. External overall length of the SD-1X ranges from 66 to 84 mm.

For exceptionally long eyepieces, the eyepiece projection adapter may be extended by using one or more of the Borg adapters:

  • 7506 - 10 mm extension
  • 7508 - 20 mm extension
  • 7505 - 40 mm extension
  • 7509 - 60 mm extension

The eyepiece holder incorporates two setscrews to assure a firm grip on the eyepiece. Built-in rotation capability for the camera allows for versatile composition of shots. Three screws in the rotator allow for easy access to the eyepiece compartment for quick eyepiece changes.

All scope coupling and camera coupling parts are interchangeable with the larger SD-2X eyepiece projection adapter.
