The Askar M54/M48 Focal Plane Adjuster is an innovative corrector used to precisely align the photosensitive matrix with the optical axis of the telescope.

The Askar M54/M48 Focal Plane Adjuster is equipped with an innovative image plane position adjustment system that allows for perfect adjustment of the camera matrix position without affecting the working distance, as is the case with traditional correctors of this type using three-point adjustment. Maintaining a constant working distance minimizes the risk of deterioration of image quality at the edges of the image.

The adapter's adjustment ring is graduated, allowing precise reading of the current compensation range of the image plane tilt angle.
