Omegon Pro Veil SII Filters<\/strong> - see sulfur nebulae also in light pollution<\/strong>
Looking through your telescope and faint nebulae disappear in ambient light? The Omegon Pro Veil SII 7nm filter solves that. It blocks interfering light and lets only the red-orange light from ionized sulfur atoms through. Thus, faint planetary nebulae, supernova remnants and emission nebulae stand out immediately.<\/p>\n\n\n\n

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

Higher contrast, clear structures<\/strong>
The selective pass-through darkens the background and highlights fine nebular structures. Even from an urban area, you can see details that would otherwise be lost.<\/p>\n\n\n\n

For visual and photographic use<\/strong>
The filter works extremely well with the naked eye, as well as with monochromatic cameras. Combine it with H-alpha and OIII filters for full color images of nebulae. Thus, delicate structures come out contrasty and clear.<\/p>\n\n\n\n

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

Sturdy and easy to use<\/strong>
The glass sits in a rugged aluminum mount. You simply screw it into your 2\u2033 eyepiece or camera adapter. No fuss, just point and watch.<\/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
