Optical scheme of the new wide-field
telescope of the telescope network of Odessa Obser-
vatory is described.The telescope optical layout is
designed as a mirror-lens system with a Ross-type
two-lens corrector and a hyperbolic primary mirror
with diameter of 600 mm. The prime focus corrector
is capable of imaging a field of 2 degrees, the root-
mean-square radius of the diffraction spot is about
4.5 µm, which is 2.5 times larger than that of the
diffraction-limited spot (Airy disk).
