Omegon Pro Veil SII Filter - see sulfur nebulae even in light pollution<\/strong>
Looking through your telescope and faint nebulae disappear in ambient light? The Omegon Pro Veil SII 3nm filter solves that immediately. The filter blocks interfering artificial light and allows only the red-orange light from ionized sulfur atoms to pass through. This makes faint planetary nebulae, supernova remnants and emission nebulae stand out immediately.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

More contrast and fine textures<\/strong>
The narrow pass of the SII filter darkens the background and highlights delicate nebular structures. Even under urban light pollution, you can see subtle details that normally disappear.<\/p>\n\n\n\n

For visual and photographic use<\/strong>
The filter works great for observation by eye, as well as with monochromatic cameras. Combine it with H-alpha and OIII filters for full color images of nebulae. This will bring out all structures contrastingly and clearly.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Simple and durable<\/strong>
The high-quality glass sits in a sturdy aluminum mount. You screw it directly into your 2\u2033 eyepiece or camera adapter. No settings required. Just aim and enjoy.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Emission nebulae: excellent fit
\u2713 Planetary nebulae: very detailed
\u2713 Supernova residues: highly suitable
\u2713 Deep-sky (SII objects): more contrast and details visible
\u2717 Galaxies: not suitable
\u2717 Reflection nebulae: not suitable<\/p>\n\n\n\n
