Mounting ideas for binos and scope
For some reason I was confident, around 7 months ago when I ordered my
20x100 binoculars that mounting them would be easy. The results are almost catastrophic. I had an engineer built a "T" bracket, which screws on top of my professional Chinon tripod. "T"s head contains holder rings, which nicely accept my Tasco. "T"s bottom contains a hole which accepts a butterfly screw that goes under the 20x100. I have arranged for the difference in weight, so all is well in terms of design. As it turns out, although correct, the entire system is dysfunctional. The tripod's altitude and azimuth controls, although robust, become extremely hard to control, when the viewing angle is ~40-45 degrees above the horizontal. The rotation of the tripod head causes the rotation of the support bracket T and as a result, the center of mass moves off approximately 10-12cms away from the tripod head. The total weight of the system head being around 9 lb., it becomes a Herculean task to rotate the head without some serious effort, when the angle is large. Does anybody know of an alternative patent that would minimize displacement of the center of mass on my system? The way I understand it, rectangular brackets won't be much of an improvement, but I am not 100% sure. I am of course interested in keeping the two optical systems aligned, that's why all the fuss. The Tasco and the binos point at the same point. What about adding counterweights on the head? Seems to be the reasonable solution. Ideas welcome, and thanks in advance, -- I. N.

Mounting ideas for binos and scope
Look at the parallelogram mounts that are sold commercially. These are easy to
build, and even easier to buy! The beauty of this type of mount is that when you have an object centered in the field, you can push the mount downward several feet so that a much shorter person can look and the object remains centered in the eyepieces. I bought one for my giant binocs and take it to every star party. Clear skies.
