1. A microscope system comprising:
an eyepiece;
an objective that guides light from a sample to the eyepiece;
a tube lens that is disposed on a light path between the eyepiece and the objective and forms an optical image of the sample based on light therefrom;
a projection apparatus that projects a projection image including a first assistance image onto an image plane on which the optical image is formed, and a second assistance image indicating a position within the first assistance image that corresponds to the optical image; and
a processor that performs processes,
wherein:
the processes include generating projection image data representing the projection image,
the first assistance image is an image of the sample in which a region wider than an actual field of view corresponding to the optical image is seen,
the first assistance image is projected onto a portion of the image plane that is close to an outer edge of the optical image, and
the projection apparatus projects the second projection image onto the position within the first assistance image projected onto the image plane.
