Claim Text:
1. An anamorphotic telescope, having mutually different magnification along directions of minimum and maximum magnification in an image plane, the anamorphotic telescope comprising a first and second reflector lens, the first reflector lens being oriented to direct light from a view direction of the telescope to the second reflector lens at an angle to the view direction, the second reflector lens being oriented to reflect light from the first reflector lens to the image plane, each of the first and second reflector lens comprising a reflective surface having a shape with mutually different first and second radii of curvature in first and second directions (y, x) that optically correspond to different ones of the directions of minimum and maximum magnification in the image plane respectively, wherein at least one of the first and second reflector lens has a variable radius of curvature in the second direction (x), which varies as a function of position in the first direction (y), the variable radius of curvature decreasing continually over said at least one of the first and second reflector lens in the direction of a first direction component of displacement from points along the view direction to points along a path of the light directed by the first reflector lens to the second reflector lens.
