APM offers you a comprehensive selection of different telescopes for every requirement and budget. We can offer you various mirror telescopes, refractors and catadioptric telescopes, from a simple entry-level telescope to a 1.5m observatory telescope.
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.
