<P>PROBLEM TO BE SOLVED: To provide a telescope which allows an image of an object formed by a single objective optical system to be observed binocularly and has a reduced entire length. Ž<P>SOLUTION: The telescope 1 includes: in order from an object side, an objective optical system 2 forming a primary image A of the object; a relay optical system 4 relaying the primary image A to form a secondary image B; and a binocular optical system 5 including an optical path dividing means 7 dividing an optical path from the relay optical system 4 into two, and a pair of eyepiece optical systems 5a and 5b guiding the optical path divided by the optical path dividing means 7 to both eyes. The telescope 1 includes a deflection optical system 3 forming a deflection optical path deflecting the optical path in the telescope 1 and traveling to the side of the object, in the relay optical system 4 and the binocular optical system 5.
