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