Alpen Wings ED 10x42 - Alignment/collimation correction? (1 Viewer)

[WJC]

I neglected to close this topic.

Explore Scientific honored the Alpen lifetime warranty. They successfully collimated the binoculars, at no charge to me, and returned them to me. I checked the collimation and it is now GOOD.

So, I now have a pair of bins that I won't worry about at all - like having a pair of bins you don't mind other people using (loaner). These have very good image and mechanical quality. Surprisingly good, as I compare them to my much more expensive bins.

All's well that ends well. Thanks to Explore Scientific.

Both their collimator and their ONCE tech used to be mine.

Is the tech Ian Xu aka Ivansky on the cloudnights forum? [email protected]

William J Cook is now retired. His state of the art equipment is now owned by Ian Xu who is known as "Ivansky". You can find Ivan's posts right here on CN occasionally. He does a superb job repairing binoculars.

I don’t know who Ian Xu is and I didn't sell him my collimator. But I do know my, “state of the art” equipment was NEVER “state of the art” even when it WAS state of the art. It’s basically an f/4 reflector telescope ... backwards—with a full-aperture reticle at the focus! I do know the 7-inch model had an aspheric objective. (I have one of those, too.) The 10-inch model had an objective of 2 convex-plano (plate glass) lenses. That’s all that was needed; don’t start stacking BBs on me, here. The US NAVY came up with the technology out of the need just prior to WWII, probably at the California Academy of Science on the peninsula across from Alameda. Before the Mk5, the Navy was using the Brit idea of the Mark I, which ALWAYS was dependent on the tech’s spatial accommodation and which the British Army considered outmoded as early as 1941.

I also know Orion has a copper clad version that I once owned and sold them as well as the copper-clad version I sold to Mike Rivkin of Deutsch Optik which now is owned by Kevin Busarow of Oberwerk.

Cory and I spent over 10 years trying to tell him he needed a Collimator. But, each time, he came back with how he didn’t need a collimator because he could, “Eyeball collimation to 100 power.” I had not created “spatial accommodation” at that time, but we both understood the concept and knew he was very wrong, especially since he was advertising all his binoculars as being “perfectly” collimated.

Kevin was friend, then. I consider him a friend, now. But I must admit I was not impressed when his Oberwerk created 2 video tapes to say, “conditional alignment” was a myth! Profiteering off the propagation of BAD SCIENCE?! Shame on him. I am certain he didn’t do it intentionally; he just didn’t understand the physiology of spatial accommodation. It was one of the two reasons why I said:

“There’s a big difference between 20 years’ experience and 1 year of experience 20 times.”

Fortunately, Kevin attended one of Cory’s binocular collimation seminars. He now owns a collimator, has been taught how to use it, and understands spatial accommodation.

Thank you for that. However, as John Wayne was supposed to have said:

"I am only responsible for what I say. not for what you understand." I sold this fellow nothing and my Collimator is safely in my garage.
