The flattener, also known as a field flattener, is a lens designed to rectify the slight curvature of the field caused by the primary optics. This curvature can result in less sharp stars at the edges of the field of view. By using a flattener, astrophotographers can ensure that stars remain crisp and well-defined across the entire exposure.
