Lacerta Universal Field Flattener 2" (82800)

A flattener is an optical accessory designed to correct the natural curvature of the field produced by a telescope's primary optics. This curvature can cause stars at the edges of the field of view to appear less sharp, which is particularly problematic in astrophotography. By using a flattener, also known as a field flattener, this effect is corrected, ensuring that stars remain sharp and well-defined across the entire image. The flattener is positioned between the telescope and the camera, making it an essential tool for astrophotographers seeking high-quality results.
