Characteristics:
- Universal Reducer/Flattener for many Apochromats
- High quality optics, calculated by Massimo Riccardi
- High-quality multi coatings
- Excellent image quality up to full frame sensors
Massimo Riccardi, well-known optical designer from Italy, has calculated a high-quality 3-lens 0.75x reducer / flattener for APM-LZOS apochromatic telescopes, which is also suitable for many apos from other manufacturers. The reducer reduces the focal length by a quarter and corrects the image field. Use it to transform your telescope into a fast astrograph! The connection to the telescope and the camera is made via an M82x1 thread. We can also offer an adjustment flange for precise adjustment if the reducer / flattener is tilted.
The back focus is adjusted depending on the telescope used. The exact value for your scope can be found in the PDF documents below. The total optical length of the reducer + back focus + focus shift is between 185mm and 210mm. For focusers with a free aperture of 90mm, the reducer can also be countersunk into the focuser with an adapter. The correction is designed up to full format and is also suitable for the widely used Kodak KAF 8300 sensor.
