A microscope system includes a microscope apparatus and a computing device. The microscope apparatus obtains image data of a surface to be observed of a sample in each of the plurality of states having different setting values of a correction collar. The computing device calculates an evaluation value of image data on the basis of each of the plural pieces of image data. A process in which the microscope apparatus obtains the plural pieces of image data is repeated in such a way that a distribution range and an average interval of the setting values are narrowed in each repetition, and that the setting value that corresponds to a maximum evaluation value is included within the distribution range. The computing device calculates the setting value for correcting a spherical aberration on the basis of the evaluation values and the setting values that correspond to the evaluation values.
