Telescope Mount


A brass stand on a heavy iron tripod base. At the top of the stand there are two v-shaped holders to cup a telescope. Beneath this there is a knurled knob; when loosened, this allows the holders and the support below to rotate, also turning a long metal pointer. This pointer rests on a graduated section that sticks out from the stand perpendicularly. It is graduated from 0 (at one edge), to 30 (at another), with 15 in the middle.

Two additional knurled knobs allow the stand to be fixed in a raised position, and to allow the vertical orientation of the telescope to be adjusted.

This object is a simple stand for a telescope.


Good: This metal and painted surfaces of the stand are scratched, particularly on the corners. On the v-shaped holders at the very top of the stand, there are indications of where a telescope has been rested repeatedly in the Vs. On the top of the stand there are traces of a brown material, perhaps felt, that provided a cushion for the telescope. The surface of the metal pointer has uniformly gone rusty; other evidence of mild corrosion exists on the tripod base where the paint has been scratched off.
