BinocularSky Posted March 18, 2019 Share Posted March 18, 2019 Not entirely sure, so do check with others, but: A photo or two would help but, if they are the ones I think they are, I think the objectives are held in place by retaining rings. If so, you'll likely need a peg spanner to remove them. It probably collimates with eccentric rings, so you'll need to mark the exact position of those before you dismantle it; also a good idea to return the lenses in the same orientation - marking their rims with a pencil can aid this.
