  • Bayonet adapter to fit suitable 1¼" astro-eyepieces onto all Carl Zeiss Diascope Fluorit spotting scopes
  • includes Allen Wrench key and two O-rings to adjust stiffness when switching eyepieces

For astronomical use, you need a fast eyepiece change, without changing the orientation of the Diascope. We therefore provide the eyepiece adapter without a mounted sealing ring, so that the eyepieces can be switched easily. The bayonet has got an groove, which serves to receive one of the two supplied O-rings. If you prefer a sealing ring, you can adjust the stiffness when switching eyepieces between tight (large O-ring) and light (small Oring) with these two different rings. The image shows the undercut to place the O-Rings
