The binocular collimation page Rich referred to is at: http://www.cloudynights.com/ This is THE site for reviews, data, repair, and general information on large binoculars for astronomy. There you will find the link to the page describing how to collimate a pair of Bear 15x70mm binos. It is straighforward and accurate and works for the Galileos and Oberwerks too since they are really the same binocular. I've collimated two pair of Bears and Glen Warchol has collimated a pair of Galileos successfully, using the same procedure. It can take patience if you've got a stubborn unit. One of the ones I did was easy, one raised my blood-pressure. Make sure one side is reasonably well centered before blindly moving the other side. Most of the time only one side need be adjusted; pick the right one. C. __________________________________ Do you Yahoo!? The New Yahoo!
