Descrizione prodotto

Again and again we were made aware of customers that the combination of the moon & Skyglow filter and the Fringe killer color-corrected images in amazingly Billi-refractors supplies. Unfortunately reflexes were complaining that occurred in such a combination.

With this filter you can confront the problem. It causes a practically neutral color image without the blue and red halo, which reduces the cheap refractors in the image contrast so annoying to be seen.

Commento del nostro esperto:

Purtroppo, questa descrizione non è stato tradotto in italiano, in modo da trovare a questo punto una descrizione inglese.

The Fringekiller blocks about a third of the blue light. The transmission in red and green light is 100%. The resulting loss of light over the entire spectrum is only about 12%.

The semi-apo filter blocks more than 25% in blue and red light. The proportion is lower in green, but about 30% of light is lost across the entire spectrum. But the colours are once again neutral, except for a slight green tint. The light reducing effect of the semi-apo filter is about half a stop.
