<p>PROBLEM TO BE SOLVED: To provide an imaging device and a telescope capable of easily adjusting the framing to a desired subject even during tele-photographing without size increase.SOLUTION: An imaging device 1 has: a main body unit 100 that collects light from a subject area via an imaging optical system 2 provided on the front face side facing a subject, receives light, and performs photoelectric conversion to create image data; a light source unit 821 that emits light; and a reflection optical element 822 that transmits the light from the subject area and reflects the light emitted from the light source unit 821 toward the rear face side opposite to the front face. The imaging device 1 further includes an optical focusing unit 820 that creates a virtual image of the light emitted from the light source unit 821 in the subject area or in the vicinity of the subject area, and a leg part 810 that holds at least the reflection optical element 822 movable in a direction separated away from the main body unit 100 and orthogonal to the optical axis O of the imaging optical system 2 at the start-up of the optical focusing unit 820.</p> |
