A field flattener is a lens designed to correct the natural field curvature produced by primary telescope optics. This curvature can make stars at the edge of an image appear less sharp. By using a flattener, also known as a field flattener, this effect is corrected, resulting in astrophotography images where stars are sharp all the way to the edge. The flattener is positioned between the telescope and the camera.
