Re: Objective lock-ring collimation

typically, objective collimation is accomplished in better binoculars by eccentric rings that actually hold the objective in position, but allow tuning it to change the position of the center of the lens.
These various binoculars that simply have a retaining ring that can be loosened and retightened and that allow you to wiggle the objective lens are not really intended to be adjusted at the objective. You get lucky if you have just enough room to center objectives in this instance.
I have a pair of older Celestron 20x80s that I and trying to center this way. What makes it more difficult is the retaining ring is on the inside. So the entire objective lens cell must be removed to tighten/loosen the retaining ring. The objective can be moved ever so slightly.
