A compact telescope having a modified Gregorian design comprising three reflecting surfaces. The first reflecting surface is concave and is defined by an outer perimeter and an inner perimeter. The curvature of the first reflecting surface defines a focal plane of the first reflecting surface. The second reflecting surface is optically coupled to the first reflecting surface and is disposed between the first reflecting surface and the focal plane defined by the first reflecting surface. The third reflecting surface is concave and is disposed within the inner perimeter of the first reflecting surface. The curvature of the third reflecting surface is greater than the curvature of the first reflecting surface. The third reflecting surface is optically coupled to the first reflecting surface by the second reflecting surface. An aperture is disposed within the third reflecting surface. Thus light incident upon the first reflecting surface is directed through the aperture.
