SkyWatcher 0.85x Focal/Reducer corrector For EvoStar 120ED
The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astro photography. The flattener reduces the telescope’s focal length by the factor of 0.85 and increases the useful field. As a positive side effect, the necessary integration times are significantly reduced. The field curvature that is unavoidable at most telescope systems is reduced to a nearly irrelevant level when using sensors up to APS-C format (24 x 16 mm)
The Reducers & Flatteners advantages
- Optimized for this particular refractor guaranteeing optimal results
- Better field illumination by M48 system – less vignetting compared with T2 systems.
- No expensive additional adapters necessary
SkyWatcher 0.85x Focal/Reducer corrector For EvoStar 120ED is recommended for the following telescopes
- Skywatcher ED 120/900 (Pro Serie, Evostar ED120 …)
- Celestron ED 120/900
- Vixen ED 120/900
