0.85x reducer corrector designed for astrophotography with the Sky-Watcher Evostar 72ED PRO. It reduces the telescope focal length by a factor of 0.85x while significantly improving field-edge correction.
Designed for astrophotography, the Sky-Watcher 0.85x reducer corrector is optimised for the Evostar 72ED PRO refractor.
Its purpose is twofold: reducing the telescope focal length by a factor of 0.85x and improving correction towards the edges of the image field.
This combination adapts the Evostar 72ED PRO for photographic use while providing improved field-edge correction.
A thumbscrew-fit adaptor is supplied.
