In determining the object to be observed, it is possible to detect the focus adjustment of the optical device 50 and determine that the object is the object to be observed by focusing.
Further, the data related to the observation object acquired by the related information acquisition circuit 30 is continuously transmitted from the relay means transmission circuit 28 in real time and displayed on the relay means display device 29.

The brightness in the illumination 62 is determined by the dimming in the dimming circuit 60b, and the display means 90 is displayed with the light from the illumination 62. The illumination 62 is designed so as not to affect dark adaptation by using red light. Visual cells that sense the light of the human eye include rod cells that react only to light and dark and cone cells that react to color. In particular, L pyramidal cells that respond to red have sensitivity beyond the spectral range of rod cells (600 nm or more). For this reason, when displayed with 600 nm or more red light that stops the rod cells from reacting, the display is recognized by the L cone cells that react to the red light, preventing the degradation of rhodopsin, and dark adaptation of the rod cells. Can be suppressed.

By displaying with, the data content can be reconfirmed by a fixed display as still image data. Still image data transmitted to the relay unit 20 may be stored in the storage unit 32 together with data output from the device detection processing circuit 55. Note that the captured data may be moving image data. In this case, starting from the time when the fixed capture setting device 64a is operated, moving image data is captured until the operation is performed again or for a predetermined time from the operation.

As described above, when the fixed capture means 64 for capturing the display of the imaging device 63 is provided, the data relating to the observation object is fixed without being updated, and the display is maintained and stored, so that the optical apparatus Data contents can be reconfirmed without maintaining 50 in the observed object.
