A three-camera instrument on an equatorial fork mount, set up outdoors

An equatorial fork mount, carrying three cameras, on a temporary stand. On the left is a plank of wood, planted vertically, carrying a mechanical device consisting of a chain, weights, and gears. The chain runs to the mount and is presumably a drive mechanism. The cluster of cameras consists of a larger central one, flanked by smaller units. Beneath the rectangular stand is a battery. In the background is a garden with a number of fruit trees, a low wall or dam, a hedge, and several trees. Unidentified location. One of six related images, of which this is the only one showing the reverse of the setup. See also PLB16_0013. n/a. Extent: 1 glass plate.
