Q: 5. I purchased a pair of 10x50 Celestron Nature DX ED binoculars and the Celestron Binocular Tripod Adapter. It is not obvious how to connect them, since each of these has a male 1/4-20 screw. There is not a female-to-female adapter to connect them, except for a very thin nut, which may or may not be 1/4-20 (it is very loose on the male threads). Is there a more detailed diagram showing how to mount the binoculars on the tripod adapter?

A: I figured out the problem. The logo cap that is described in the manual is firmly attached to the binocular's female threaded screw. Thus, when I tried to remove the logo cap the female threaded screw was coming off with the logo cap. Once I was able to separate the logo cap from the female threaded screw (with quite a bit of effort), I was able to thread the screw back onto the binoculars, allowing the tripod mount to be attached. Unfortunately the manuals provided by Celestron don't show enough detail for the user to see what the female threaded screw should look like.

Q: 6. Why do some Vortex Viper hd 10x50 binoculars have straight barrels while others show expanded barrels at the front (lens)?
