If you want to achieve the iconic look of Hubble Space Telescope (HST) images, such as the famous “Pillars of Creation” in the Eagle Nebula (Messier 16), the SII filter is an excellent addition to your collection after H-alpha (H-a) and OIII filters. Like the H-a filter, the SII filter is a deep red filter near 672 nm. Together, H-a, OIII, and SII filters enable tri-color narrowband imaging to replicate that Hubble-like appearance for many emission nebulae.
