This useful device is essentially a "weight carrier" which fits on Astro-Physics 1,125" counterweight shafts and allows one to attach 2 1,5l bottles - depending of the bottle (water as featured, wine ;-) allows up to roughly 4kg of counterweight - enough to balance FSQ85 with Canon DSLR and 200mm lens mounted side by side on my lightweight plate.

The carrier is made from few pieces of pine wood, glued and bolted and finished with a transparent water lacquer. A small metal insert placed in one of the wooden pieces allows me to secure the weight with a section of M6 brass rod.

Another "cost saver" for those traveling by air to remote locations.
