Collimation help needed

[enigma]

Does anyone know how to collimate the Helios Quantum 3 20x80 binoculars?

The rubber on these binoculars seems to be permanently glued to the body to hide any collimation screws.

I'm not familiar with this particular binocular  but some 80mm objectives have eccentric holders that can be rotated once the outer retaining ring is loosened, this provides a collimation facility.

No idea on the Helios but there's a few people here that should be able to point you in the right direction, there's a guy called Steve Tonkin who's regularly on here, screen name is BinocularSky he may be able to give you some advice, he's the author of a great little book called binocular astronomy, give him a PM, he seems a nice chap

he seems a nice chap

He does, doesn't he?

But sorry, I've not had that sort of relationship with a Q3 (yet). I'll try to find out (but it won't be for a few days, probably, as life is hellish hectic at least until Friday).
