Sky-Watcher 0.85x focal length reduction and field corrector for ED refractors 80/600
... reduces the focal length, increases the light intensity and corrects the field of view for astrophotography
The Sky-Watcher 0.85x focal length reducer and field flattener has been developed for the dedicated astrophotographer, who wants to make full use of the well-known ED 80/600mm also for astrophotography. The flattener reduces the focal length of the refractor to 510mm with an aperture ratio of f/6.3. In this case, the image field is extended to the corners of the recording format, e.g. corrected by DSLR cameras very well.
The advantages of Reducers & Flatteners:
- Optimized for this refractor, ensuring optimal results despite the shortening - Better illumination than with reducers with T2 connection - also suitable for full format chips - No expensive additional adapter needed
The flattener is suitable for the following telescopes:
- Skywatcher ED 80/600 (Pro series, Evostar ED80 ...) - Celestron ED 80/600 - Vixen ED 80/600
Technical specifications:
- Telescope side ... matching thread for screwing to the focuser - On the camera side ... M48 thread for more illumination - suitable T-rings for DSLR cameras to find under recommended equipment - Distance from the M48 thread to the optimal focus position ... 55mm (this is exactly a DSLR camera + T-ring)
