Two-element reducer/flattener with an ED element. Reduces the standard focal length of the Evolux-82ED by a factor of 0.9x and provides the best image field correction all the way to the edges. The reducer/flattener allows full frame and delivers pinpoint stars like needle points on a 36 mm image field.
The resulting focal length is 477 mm for an aperture ratio of f/5.8. The maximum field of view is thus 4.34°. The backfocus is 55mm. All lenses are fully multi-coated.
A field adapter/rotator with thread for 2" filters is included in the delivery. It features a telescope connection thread of M56x1 as well as a camera thread of M48. It can be adapted to the corresponding camera using optional Sky-Watcher adapter rings from M48 to Canon and Nikon (products no. 20237 & 20238).
