Re: Collminating binoculars
If you have found the 4 adjustments on each barrel you must have a verticle (telephone pole) and horizontal line (peak of a house roof) to Collimate them.
A collimater for the closer range is best and some camera and binocular shops have one.
If they are knocked out to badly, you may have to send them back to the factory.
You have to look in the one tube and set the hoizontal line (house roof) at the very bottom of the tube or view. Make sure the binocular is on the tripod so it doesen't move. look in the other barrel (tube) and see where it is alighned. If it is different then the other, you must make the adjustment on THAT tube to get it to have the horizontal line at the same place as the other tube.
Now when that is set, go to a verticle line such as a telephone pole. Set the pole in your view so it is at the very right hand side of the right tube and barely visable. Lock it at that point in the tripod. Now go to the left tube and make sure it is verticle at the very right side of that tube. If it's not, make the adjustment to align like the other side.
You may have to do this 2 or 3 times to each to align it perfectly.
This is the way the bigeyes in brackets are done and the binoculars are the same as long as you have 4 adjusters on each tube. A top, bottom, right and left.
