Skywatcher - 0.85x Focal Reducer/corrector for Evostar-80ED DS-PRO

Skywatcher 0.85x focal reducer and field flattener for 80/600mm ED refractor

Increases the field of view and photographic speed, and corrects for field curvature

Skywatcher Field Flattener for ED refractors

The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astrophotography. 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 (24x16mm).
Optimal distance M48 - focal plane: 55mm
