For when I DO get the cataract fixed, I have seen no reference or diagrams as exactly WHERE on the neck the convergence yoke is placed, ( how far forward / back ) I can make a guess based on the markings, but, I have not seen it written anywhere that I can find, nor have I seen something for placement of purity rings or blue lateral.
Placement of them is probably not super critical, but then again, I can imagine that the placement of them a few degrees forward / back would have a visual effect. And find it a little hard to believe that there is no instructions / diagram someplace saying “this goes aprox here,” and so on.
Also, I have found the static convergence magnets quite hard to manipulate / adjust, no doubt have gotten tight over the years, any known way to make them slide easier for when final convergence is done?
Thanx.
