The Askar 0.8x Reducer for 140APO Telescope is an essential accessory for astrophotography. Firstly, it increases the focal ratio of the Askar 140APO telescope to f/5.6, significantly reducing the time required for image capture. Secondly, it corrects optical aberrations at the edges of the image, ensuring perfectly pinpoint star images across the entire field of view during image capture.
The reducer features a 44 mm image circle, making it perfectly suitable for use with full-frame cameras. On the camera side, M48 and M54 threads are available, allowing for wide compatibility with various systems. With an M48 connection, the classic 55 mm sensor distance is achieved, which increases to 73 mm when using the M54 thread.
