摘要：<P>PROBLEM TO BE SOLVED: To provide an optical apparatus, a telescope body and a telescope that can obtain a photographic image of high picture quality with small color blur due to longitudinal chromatic aberration with simple and inexpensive constitution. <P>SOLUTION: The terrestrial telescope body 1 comprises an objective optical system 11, a focusing lens 31, a beam splitter 56, an imaging optical system comprising a reduction optical system and an optical filter unit 17, a CCD imaging element 16 which picks up a subject image formed through the imaging optical system, a reduction optical system driving mechanism 19 as a focus driving means of moving the imaging position of the subject image, and a control means of controlling the CCD imaging element 16 and reduction optical system driving mechanism 19. The control means is capable of control for successively taking a normal photographic image and a specified-color-focusing-position corrected image photographed in a state wherein the driving position of the reduction optical system driving mechanism 19 is corrected so that a specified-color component causing longitudinal chromatic aberration in light incident on a photodetection surface 161 is put in focus. <P>COPYRIGHT: (C)2005,JPO&NCIPI
