Japon miror Quality!
Astrophotographers generally use two different focal lengths: Short focal lengths for overview photos and extensive deep-sky objects, and long focal lengths for objects which are further away. Our aspherical mirror optics offer the perfect solution for these scenarios. The VISAC primary mirror (Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and provides a fully flat and true-colour image over the entire image frame. Thanks to the three-element field corrector in front of the convex secondary mirror, there is no spherical aberration, coma or field curvature. Although the device is designed for astrophotography, it is also suitable for visual observations.
