Phantom Group coated. Fringe Killer 1.25″ – contrast increase
and reduction of chromatic aberration in refractors
The Fringe Killer is an evolution of the simple minus
Violet Filters. It lets through a little more of the light in the blue,
so that the image is not colored as much. In addition, the
Contrast increased significantly. Filter thickness 2mm.
For refractors from 70mm aperture to 150mm aperture – if it is a
moderate reduction of the chromatic aberration goes, with simultaneous
increase in contrast.
Areas of application:
Moon and planets: the contrast is increased, the recognition finer
detail increases
Earth observation: here, too, the contrast is increased
Double stars: the resolution increases because of the color fringe around the stars
is reduced.
Astrophotography: here, too, the contrast increases and the stars become
smaller. IR is completely blocked.
