PROBLEM TO BE SOLVED: To provide an optical apparatus, a focus control method therefor, and a spacecraft with which it is possible to obtain high-clarity image by an optical telescope mounted in the spacecraft.SOLUTION: An optical apparatus (100) that includes image formation optical systems (101-105) and is mounted in a spacecraft (20) includes: first focus adjustment means (107) for correcting a change of focal length due to the deformation of the image formation optical systems; and second focus adjustment means (200) for correcting a change of focal length due to a change of distance between the image formation optical systems and a point to be observed.SELECTED DRAWING: Figure 4
