The ToupTek Astro M54 Focal Plane Tilt Adapter (tilter) is designed for ToupTek Astro's cooled SkyEye series cameras. It enables precise adjustment of the camera's tilt angle, thereby correcting minor misalignments relative to the optical axis.
A key advantage is its rear-adjustable design, meaning the adjustment screws remain accessible even when assembled with accessories such as a filter wheel, filter drawer, etc.
