Stabilizer for Bino Parallelogram

I may have pointed this out before, but it could be worth repeating. If you have or are considering building your own bino parallelogram, one problem can be balance or stabilization of the mount, especially with larger binos (+80mm). This can be solved by inserting a reverse thread rod from a wood clamp as shown in the photo. The threaded pins in the wood screw are inserted in the parallelogram rods. This assembly maintains the binos in their position even if the mount is not perfectly balanced. Granted, it will not be silky smooth, but it works.

I had noticed the balance of the mount changing as the angle of the binos changed due to the weight of the lenses. This is no longer a problem. You do have to twist the screws to adjust for vertical position.

That's a really cool idea!

My mount is an older commercial affair that is made of aluminum. Although it works OK with my Celestron 20x80's, there is always a pretty long vibration damping cycle, and it vibrates in moderate wind. I would suspect that your wood mount is much better with damping vibration.
