I am selling my custom made binocular mount. Price is $300 and pickup only. Call or text me at 864-901-8725.
There are many lightweight mounts for smaller binoculars (~5 lb models) but not so many for large astronomical binoculars. The closest commercial (the Para-Light Combo) one can be seen at https://www.ontariotelescope.com/Para-Light-I-Parallelogram-Combo_p_1098.html
The tripod/mount can be taken apart for transporting to a dark location, but I'm getting a little too old for this. The mount weighs about 50 lbs and it is perfect for terrestrial viewing from a covered deck or sunroom.
I use a Manfrotto MVH502AH Pro Video Head but this head and the binoculars seen in the photos are not included. This head easily holds my Apogee 88mm-90 degree and my Zhumell 25x 100mm binoculars. You can use any binocular head that you have or rather use that accepts the standard 3/8" connection.
The telescopes in the background should give you a sense of the size of this mount. One telescope is a Celestron 8SE on the HD tripod.
