A reducer for small CCD chips. This 2-element reducer makes no correcture but it reduces the focal lengh to 0.75x. The reducer is good, if you only want to have a good correcture on the optical axis but not in the edges.
- Raises the focal length from f/8 to f/6.
- For sensor diagonals to 15mm diameter
- Working distance: > 80mm - enough space for off-axis- guiders and filter wheels
- Telescope side: 2" barrel with M48 filter thread
- Camera side: male M48x0.75 thread
