Is there any way to completely disassemble these binoculars to restore the retaining clips to a functional level? Right now there is no way to collimate them at all - the best I can do involves some horizontal skew at infinity. -drl Post Extras:       KennyJ Reged: 04/27/03 Posts: 10029 Loc: Lancashire UK Re: Konus 20x80 Headache model [Re: deSitter]       #2495878 - 07/02/08 05:37 PM Edit   Reply   Quote Quick Reply   drl , Is this model actually called 20 x 80 Headache ? The name should be on the prism housing cover . If it is a genuine " Headache " model , then no mechanical adjustment will ever prevent it from giving users a headache . There have been many imitations of this rare model produced in recent times , some of which can be adjusted quite easily , at least to provide alignment for one fixed IPD . Good luck !
