Hi Dion, Seth is right, it is really expensive to have someone collimate your binoculars. If they are so bad that they are useless, and if you are a gung-ho DIYer, you may want to look at this article and see whether anything in it can carry-over into your situation. http://www.cloudynights.com/item.php?item_id=416 Also, if you do a google search on" binocular collimation", and "binocular adjustment", you will get a few articles and you-tube videos that may be useful.

If the barrels will unscrew, you might be able to fix your issue by removing the barrel and then screwing it back in. I had this happen to mine once and it fixed the issue. I think they must have just been bumped and the treading was just plastic.
Thanks, David Dunn

I agree that you probably do not want to send the binoculars for repair as it would not be cost effective. I have aligned binocs "good enough" simply by bending them myself. If that does not work, or you break them in the process, well then, you get to buy another pair! If that ends up being the case, you can be satisfied that you tried to fix them yourself.

Dion,
If the optics of each half of the binoculars are crisp and focusable over a wide range of distances, then your optics aren't the problem, the two halves simply aren't pointing in the same direction. When your eyes do this it's called diplopia.
I've had the same problem (my 10x50's got dropped at a star party), and after calling the manufacturer (in my case, Celestron) and describing the problem they told me that the cost of re-aligning the barrels would cost more than just buying a new pair of binoculars. The tech I spoke with said, "You simply can't get metal to bend back to its original position and expect it to stay there. It's a matter of metal fatigue."
My two cents.
Seth

Does anyone have suggestions on where I can take my Bushnell 12x50 binoculars for repair? The eyes don't line up anymore, and nothing I do with the knobs and dials seems to fix it. I don't know if they got dropped or what. Each eye seems OK independently, but together they create nothing but headache because the two images are not aligned. Thanks, Dion
