[QUOTE="WJC, post: 3686566, member: 25191"] The main thing is you're happy! But without a collimator and the understanding of the procedure, your comment just means your spatial accommodation--at your IPD--is working well. If others with the same, or nearly the same IPD, are the only ones to use the bino life is good with nothing else needed. If that isn't the case, all bets are off. There's more than one flavor of alignment. Just like "shockproofing" being good enough, alignment can also be GOOD ENOUGH without qualifying as the clinical, 3-axis "collimation" sought at the factory. But, unless you have a desire to be an opto-geek ... don't worry about it! Use your bino and be happy knowing you have succeeded in performing a good "conditional alignment," which is not a small task. I only wanted you to know of those degrees of alignment. Take care of your specimen; it will undoubtedly rise in value. :t::cat: Cheers, Bill [/QUOTE]
