A terrestrial telescope having a digital camera includes an objective lens, an imaging element located at the image-formation plane of the objective lens, and an image processing unit for processing image data captured by the imaging element for record on recording media. A return mirror is disposed between the objective lens and the imaging element to direct the beam to an erecting optical element and an adjustable ocular during observation and direct it to the imaging element during imaging. A reticle is located conjugate to the image-formation plane of the objective lens to indicate the range of the imaging element. A controller controls the return mirror in such a way that it is retracted from the optical path when it is desired to take a picture of an object, and it moves back into the optical path to enable a user to view images of target objects.
