The Bintel 0.75x RC Reducer is a simple reducer made by GSO for cameras with smaller CCD chips. This 2 element reducer reduces the focal length to 0.75x.
Product characteristics:
- Changes the f/ratio: from f/9 to f/6.7 in 6" RC - from f/8 to f/6 in 8", 10" and 12" RC.
- Best suited to sensor diagonals up to 15mm diameter
Working distance: > 80mm - enough space for off-axis-guiders and filter wheels
Telescope side: 2" barrel with M48 filter thread
