So I've got an old pair of Orion 10x50 Worldview binos that have some of the nicest optics I've ever seen in a cheap bino. I've had them for about 7 or 8 years and they're no longer collimated. There doesn't seem to be any adjustment screws or any other way to collimate the optics. When I look through them now, I usually "pull each side" of the bino a bit so I don't see double. Of course this isn't a very practical way of observing. Any ideas on how I could align the two barrels? I was thinking of a shim or something but I'm not sure if I month make it worse. I hate to throw them away because if I could just align them they'd be outstanding. I wish there was a way to adjust them.

Wish I could help you. I can collimate the hell out of a Newt, but I've never messed with bino prisms. Honestly, I'd try to PM EdZ over on Cloudy Nights - he is a fountain of bino knowledge. He's torn apart and reassembled many units so hopefully he'd be able to help you.

Was thinking the same thing. Ed is the man. Was also thinking you could send them to Cory Suddarth, Zach Garrett's right-hand-man. He is a wizard. The only problem is shipping cost from HI for a job you're not even sure about. It depends how much it's worth to you. I'm not familiar with the build quality of those, whether mostly plastic or metal in the prism mounts, etc... If you just want a cheap fix you could construct an adjustable wedge for the front that replaces the job of your "hand-pulling".

Thanks guys. Yeah, I forgot about Ed on CN. I'll pm him and see what he says. I was looking at the moon last night and they hardly show any CA.
