Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!
Orly, did you understand what Edz said? Anyway his last statement hinted and sums it up well...as I had said, a better quality binoviewer wouldn't have that issue you have.
Furthermore, I would generally not buy a binoviewer or binocular as a used item from overseas buyer unless I am absolutely sure that person is honest and reliable, regardless of his price. For such items, I usually prefer to buy locally only upon passing my inspection. My alignment standard and tolerance is very precise, and I have very specific inspection tests on these items before I buy them. People who buy binos from me knows my binos have 100% spot-on alignment and collimation.
It's fine that you declined my offer to check yours. Anyway I hope you have resolve your problem.
