The 0.8x reducer effectively reduces the focal ratio of the Askar 103APO to F5.4, providing standard field flattening capabilities. This versatile reducer, with its triplet design, supports a 44mm full-frame image circle and weighs a mere 0.48kg. With a standard back focus of 55mm from the M48 thread and an M84*1 front thread, it offers optimal specifications.
The benefits of the shortened focal ratio include a wider field of view and faster exposure times, making the telescope well-suited for capturing expansive areas of nebulae, star clusters, and faint, fast-moving celestial objects.
At the camera end, the 0.8x reducer comes equipped with two convenient adapter sizes, M540.75 and M480.75, facilitating easy connections. Additionally, it features a built-in M48*0.75 2-inch filter thread for direct filter installation. The overall CNC machined construction, complemented by threaded metal caps at both ends, serves to prevent dust accumulation when the equipment is not in use.
