Tax included
This narrowband line filter is designed for astrophotography, specifically to enhance the visibility of emission nebulae by isolating key oxygen emission lines. By suppressing unwanted background light, it increases contrast and reveals fine structural details in nebulae. The filter is optimized for imaging rather than visual observing and is best suited for deep-sky photography under light-polluted or dark-sky conditions.

The SII narrowband filter is designed for nebula astrophotography and transmits light centered at a wavelength of 672 nm. With a narrow bandpass, it enhances contrast and isolates sulfur emission, making it well suited for imaging emission nebulae, planetary nebulae, and supernova remnants. For astrophotographers seeking the classic Hubble Space Telescope–style appearance, such as the iconic “Pillars of Creation” in the Eagle Nebula (Messier 16), the SII filter is a natural addition after H-alpha and OIII filters. Like H-alpha, SII operates in the deep red region of the spectrum near 672 nm.

Omegon Filters Pro Veil H-Alpha OIII 7nm 2'' (82000)
318.44 $
Tax included
Artificial lighting from cities and towns brightens the night sky and reduces contrast, making faint celestial objects harder to observe. While streetlights improve visibility on the ground, they create skyglow that obscures delicate deep-sky structures. Emission nebulae differ from star clusters, galaxies and reflection nebulae because they radiate light at very specific wavelengths. Instead of producing a broad spectrum, they emit distinct spectral lines.

Omegon Filters Pro Veil OIII 3nm 2'' (82014)
438.24 $
Tax included
Artificial lighting in urban and suburban areas brightens the night sky and reduces contrast, making faint deep-sky objects more difficult to observe. Skyglow caused by streetlights and industrial lighting often overwhelms delicate nebular structures. Unlike galaxies, globular clusters or reflection nebulae, emission nebulae radiate light at specific wavelengths. Because the human eye has limited sensitivity in the red spectrum, only the O-III and H-Beta lines are easily visible visually. Cameras, however, can record all these wavelengths, including the deeper red emissions.

Artificial lighting in populated areas brightens the night sky and reduces contrast, making faint deep-sky objects difficult to detect.
