Flattener / Reducer / Correctors
Corrective optics are a very important component, especially in astrophotography. They turn almost every refractor, Newtonian or other telescope into an astrograph. They flatten the image field, shorten the focal length or correct system-related image errors.
Focal length reducer for VSD90ss and VSD70ss with two ED lenses for high-end astrophotography and an illumination of 44 mm for full-frame cameras
- Elaborately designed focal length reducer for the VSD90ss/VSD70ss
- Suitable for a 24x36 full format camera
- Four lens elements in four groups for exceptionally sharp star images
- Guarantees a large illumination of the image field up to 44 mm
- Very sharp stars up to the edge of the field of view
