The Askar 0.85x reducer for the 80ED APO telescope is an essential accessory for astrophotography. On one hand, it increases the brightness of the Askar 80ED APO telescope to f/5.9, significantly reducing the time required for image capture. On the other hand, it corrects optical aberrations at the edges of the image, ensuring perfectly pinpoint star images across the entire field of view during imaging.
The reducer is optimized for APS-C sized sensors, featuring the popular M48 thread on the camera side for compatibility with various systems.
