This type of interference filter allows you to increase contrast when photographing deep sky objects. The object stands out better against the background of the night sky, allowing you to see details that were not previously apparent. The Omegon pro SII filter has been specifically designed for nebula astrophotography using CCD and DSRL astronomical cameras.

Many planetary and emission nebulae will show significant additional detail when imaged at the first frequency of ionized sulfur at 672nm. This filter allows this range of interest to pass through, but blocks stray light and artificial lighting.

With a small 'half-height peak width' of 12nm and high transmission, this filter will take you into the realm of high-end astrophotography. You will be able to create excellent deep sky images, even from big cities. And combined with the OIII- and H-alpha filters, your images will be truly eye-catching!
