Claim Text:
1. A microscope apparatus comprising: a monitoring optical system including an objective lens; a setting unit setting a focal position such that a focus of the objective lens is on an observation target; a changing unit changing the focal position set by the setting unit along an optical axis of the monitoring optical system; an imaging unit capturing an image of the observation target generated in the monitoring optical system to generate an image in a first state in which the focal position is moved by the changing unit by a first distance in a first direction, and capturing an image of the observation target generated in the monitoring optical system to generate an image in a second state in which the focal position is moved by the changing unit by the first distance in a second direction, the second direction being opposite to the first direction; a correction collar correcting aberration that occurs when the focus of the objective lens is positioned at the observation target: and an adjusting unit adjusting a rotation position of the correction collar, wherein the adjusting unit
