- Maximum Strehl ratio (as with the Zeiss APQ) is guaranteed to be 95% or better.
- Residual chromatic aberration optimized to a minimum.
- Temperature-compensating mount.

The new FS-60CB has a tube that is 20 mm shorter than the classic version (FS-60C). The original configuration can be restored using a removable 20 mm screw adapter. This allows the light path to be easily adapted to different requirements, whether 1.25‘ equipment or 2’. Even with a 2‘ zenith mirror and a 2’ eyepiece, the focus position can be easily reached.

With these reducers for the FS-60CB or FS-60C fluorite apo, the focal length can be reduced by a factor of 0.72x, from 355 mm to 255 mm (f/4.3). This combination allows you to reach ranges that are otherwise covered by telephoto lenses – with uncompromising image quality. The image circle is exceptionally large for a reducer, with a diameter of 40 mm, but it can only be recommended for full-frame cameras to a limited extent. With an APS-C sensor, however, you have almost full illumination right into the corners of the image.
