A shorter focal ratio allows the telescope OTA to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe 0.75x reducer adopts a triplet design and supports a 44mm full-frame image circle. The overall weight is 0.2 kg. The back focus from the M48 thread is a standard 55mm.
