THE flattener is a lens that flattens the field of view which is slightly curved by the primary optics. THE CURVATURE CAUSES LESS DEFINITION OF THE STARS AT THE EDGES OF THE FIELD OF VIEW. THE FLATENER, ALSO KNOWN BY THE ENGLISH TERM FIELD FLATTENER, CORRECTS THIS EFFECT. ASTROPHOTOGRAPHERS CAN THUS CREATE WELL-DEFINED PHOTOS EVEN AT THE EDGES OF THE FIELD OF VIEW. THE SPOT FIELD MOUNTS BETWEEN THE TELESCOPE AND THE CAMERA.
THIS FIELD FLATENER WAS DESIGNED FOR IOPTRON APOCHROMATIC REFRACTOR AP 108/648 ED VERSA OTA. HOWEVER, IT IS ALSO COMPATIBLE WITH REFRACTOR WITH FOCAL RATIO FROM F/5 TO AF/7.
