| 摘要 |
The invention contemplates an improved two-axis mount or adapter whereby a telescope may be mounted to a given base structure, for precise polar-axis motion and/or declination-axis motion. This is achieved in a unit-handling structure wherein a single housing provides rugged, wide-based journal support for each of two elongate shafts, orthogonally oriented and at close-clearance offset where their directions cross within the housing. One of these shafts has externally projecting provision for fixedly securing the same to desired base structure, and the other shaft has externally projecting provision for securing the telescope thereto.
