If you have already captured a nebula with H-alpha and OIII and want to add more color and structure to it, the Askar D2 filter comes into play. It allows the OIII line of oxygen and the SII line of sulfur to pass through and blocks most of the other light.<\/p>\n\n\n\n

This captures the parts of a nebula that glow in oxygen and sulfur, while light pollution and the sky background largely disappear. It fits into a method where you first take shots with a color camera the D1 filter for H-alpha and OIII<\/a> and then with this filter.<\/p>\n\n\n\n

From that combination you create an image in a narrow color palette. Expect a bit more time in the editing process, because you are combining two sets of shots. Check that your holder accepts 2-inch filters; with filter wheels and filter holders<\/a> You can see what sizes are available. The filter is intended for the night sky, not for the sun.<\/p>\n\n\n\n
