Description

Trying make bi-color version of Crescent nebula. Lumicon OIII filter gives horrible halos, destroying good picture. When I try to remove color halos - I am loosing some colors in other parts of picture, damned! Time to replace OIII filter, I am looking for Baader Planetarium CCD filter 8 nm, it looks not bad with ASI 1600. Astrodon are really good but too expensive.
