Vixen Telescope Focal Reducer V0.71x Description
-
Designed luxuriously including two ED lenses
It has a luxurious design as it contains four elements in four groups, including 2 ED lenses.
Besides, by making the lens diameter larger compared to the previous reducer V0.79x, it successfully depresses the distortion of star images at a high level even at the edge of the field of view.
Star images in the center of the field of view are perfect. -
Super fast astrograph of F3.9
The focal length of the VSD90SS/VSD70SS telescopes will be shortened by about 0.71x, and the focal ratio will be altered from 5.5 to 3.9 respectively.
It is undoubtedly your first and best choice for a super fast astrophotograph, capable of short exposure times while maintaining quality star images over the entire 44mm image circle.
