Artesky Reducer/Field Flattener 0.8x, 2"

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. Positioned between the telescope and the camera, it evens out the field, enhancing the quality of astrophotography.

The Reducer, designed for focal length reduction, is an optical accessory that offers a more favorable aperture ratio. This leads to shorter required exposure times, making the optics 'faster'. Additionally, it expands the field of view, enabling the observation or photography of even larger astronomical objects.
