High quality SD field flattener HD kit for the Vixen ED and SD refractor telescopes
With this image field plane you get razor-sharp star images up to the edge of the field of view.
The flattener illuminates a 44 mm image circle and is therefore also suitable for full format cameras.
The same anti-reflection AS coating that is also used for Vixen's high-end astrograph VSD 100 f / 3.8 enables a high light transmission of 99.9 percent per lens surface. Loss of light, ghosting and stray light images are almost completely eliminated by the completely matt interior coating.
Can be used on the SD81S, SD103S and SD 115S, as well as the predecessor ED series
Also requires the Wide Photo Adapter and a T2 ring
