Custom-made for the Sky-Watcher Pro 80ED telescope, this 0.85x Reducer Corrector provides correction to the edges of the field for superb photographic results, and reduces the focal ratio to f/6.37 to provide a larger field of view for today’s image sensors.
The Pro 80ED Reducer Corrector screws directly onto the telescope’s focuser, and is threaded to accept Sky-Watcher’s M48 camera adapters.
