Φίλτρα αστερισμών

The Kenko "soften" filter simulates high clouds or light fog, softening the appearance of stars and other bright objects in astronomical photos. By spreading the light of point sources out (see star profile graphs at right), star saturation on a digital imager is reduced, allowing the true colors of the stars to be recorded. 

Many astrophotographers find this aesthetically pleasing as well as useful particularly for wide-field photos where the bright stars of a constellation stand out compared to dimmer stars.
