Reducer / Corrector 0,9x Sky-Watcher for Evolux 62ED - Sky-Watcher

This accessory is necessary to correct the image provided by refractors (binoculars), which can produce a curved focal plane and non-point-like stars near the edges in imaging. The reducer/corrector provides a corrected image up to the edge of the field.

It is optimized for the Sky-Watcher Evolux 62ED f/6.45 (Doublet) telescope and reduces the telescope's focal length by a factor of 0.9x (induced focal ratio of f/5.8 - apparent field 5.09°).

Characteristics

• 0.9x reducer/corrector for Sky-Watcher 62ED
• Threads: M56 female at the front and M48 male at the back
• Size of corrected image circle: 30mm
• Back focus: 55mm

The use of a focal reducer in astrophotography also allows to reduce exposure time. It will be necessary to use a dedicated T-ring grand champ M48 for your camera.
