Abstract: A microscope-telescope combination fitted with an illumination apparatus of a compact and simple structure having an illumination apparatus is effectively applicable both as the illumination for the microscope and as the flashlight. A microscope-telescope combination is fitted with an illuminating apparatus comprising of a telescope optical system, an auxiliary objection lens for forming a microscope optical system arranged so as to be projected into and retracted from the front of said objective lens of said telescope optical system, and a light source supported so that its illuminaing direction is changeable to a first direction parallel to an optical axis of said telescope optical system and to a second direction directing toward an observation position of said microscope optical system.
