H-alpha Filter: This filter is designed for photographing hydrogen nebulae in both light-polluted environments and dark-sky locations. It greatly enhances the contrast between objects that emit H-alpha light and the surrounding sky background. SII Filter: The SII filter is ideal for capturing sulfur emission regions, whether you are shooting from light-polluted areas or dark skies. It significantly increases the contrast between objects glowing in the sulfur line at 672 nm and the sky background.
