TS Optics PHOTOLINE 0.79x Reducer and Corrector
The corrector reduces the focal length, increases the light intensity and corrects the field. The reducer is calculated for sensors up to full format. Unlike the Riccardi Reducer, this reducer does not require extreme back focus. It can be used in all refractors that are designed for accessories of at least 2.5" and have a focuser eyepiece from 3" or with an M68 thread.
Distance M48 thread to camera sensor
The distance depends on the focal length of the refractor:
♦ Focal length up to 350mm ... 70mm
♦ Focal length up to 420mm ... 65mm
♦ Focal length 450-500mm...61mm
♦ Focal length 510-600mm... 58mm
♦ Focal length 610-700mm ... 57mm
♦ Focal length 710-790mm...56mm
♦ Focal length from 800 mm..... 55 mm
To achieve the correct spacing, we offer extension rings and M48 tuning rings.
Connection to the telescope:
The Photoline Reducer has an external thread M68x1 on the telescope side. Many focusers already have this ZEISS level thread as an auxiliary thread. We also offer adaptations to almost all other focusers.
