The ZWO 7nm SII 7nm filter is centered around 672.4nm which is Singly Ionised Sulphur. It is in the deep red part of the spectrum and is quite common in deep sky objects. The SII filter helps to detect faint feathery detail in nebulae that’s not seen in H-alpha.
When used in conjunction with the narrowband H-alpha and narrowband OIII filters they make up part of the Hubble palette, used by HST to image these and other elements in nebulae.
