The flattener serves as a corrective lens to rectify the slight curvature introduced by the primary optics, ensuring uniform field illumination. This curvature often causes stars at the field's edge to appear less sharp. Also known as a field flattener, this accessory eliminates this effect, enabling astrophotographers to capture sharp stars throughout the entire exposure.
