The flattener is a lens that evens out the field, as this is slightly curved by the primary optics. This curvature causes stars that are imaged at the edge of the field of view to be less sharp. The flattener, also called a field flattener, corrects this effect. Astrophotographers can then enjoy images where the stars remain sharp right out to the edge of the exposure. The flattener is installed between the telescope and the camera.
This image field corrector shortens the focal length of the AP 106/700 FDC100 Apo to 525 mm and corrects the image to full format. The aperture ratio of the Apo is improved from f/6.6 to f/4.95.
- Connection to the telescope via the M63x1 external thread
- Connection of cameras via the M48x0.75 external thread and via an M82.5x0.75 external thread for special adaptations
- Working distance from the M48x0.75 thread is 55 to 60 mm – finely adjustable with 0.05 mm accuracy via an internal adjustment on the corrector
