This High-quality Field Flattener is specially designed for Vixen ED and SD refractor telescopes. With this image field flattener you get razor-sharp star images right up to the edge of the field of view. The Flattener illuminates a 44 mm image circle and is therefore suitable for the full-frame cameras.

For professional astrophotography:
The same anti-reflective AS coating is also used for the high-end astrograph VSD 100 f/3.8, which allows for a light transmission of 99.9 percent per lens surface. Light losses, reflections and scattered light is almost completely eliminated by the complete non reflective matte interior coating.
