Considerations & Trade-offs

  • Fits only eyepieces with a 1.55" (39.4mm) outside diameter, so sizing needs to be checked carefully before ordering.
  • The friction-mount, custom-fit design is secure, but it depends on a proper match to the optic rather than a universal fit.
  • It is an eyepiece cover only, so it does not provide protection for the objective lens or the rest of the scope.
  • The polymer construction is practical and lightweight, but the product data does not indicate any added padding or impact protection.
