Lunt Solar Systems Flattener/Reducer 0.8x (82799)

A flattener, also known as a field flattener, is a lens designed to correct the slight curvature of the field produced by a telescope's primary optics. Without a flattener, stars at the edge of the field of view can appear less sharp due to this curvature. By installing a flattener between the telescope and the camera, astrophotographers can achieve images where stars remain sharp all the way to the edges of the frame. This accessory is especially valuable for wide-field astrophotography, ensuring consistently crisp results across the entire image.
