This binocular holder seemed the ideal solution for my old binoculars to be, because I could fix it with the center line on my tripod. If everything went well, except for the clamping device for the binoculars! With almost every touch of the glass, it pretended to side. I had put on as firmly as possible the clamping screw, but it was not working. Already in focusing the glass came in an inclined position (my binoculars weighs just 1 kg, should not be a problem). Anyway, the binocular holder is not suitable for star gazing, he drives the blood pressure in gigantic heights.
