Omegon H-Alpha Filter - see hydrogen nebulae even in light pollution
Looking through your telescope and faint nebulae disappear in ambient light? The Omegon Pro Veil H-Alpha 7nm filter solves that. The filter blocks interfering artificial light and lets only the red light from HII regions through. This makes hydrogen nebulae, such as the Orion Nebula and Pelican Nebula, stand out immediately.

More contrast and clear structures
The selective pass-through ensures a dark background and bright nebular structures. Even from an urban area, you can see fine details that would otherwise be lost.
For visual and photographic use
The filter works extremely well with the naked eye, as well as with monochromatic cameras. Combine it with OIII and SII filters for full color images of emission nebulae. Thus, delicate structures come out contrastingly.

Robust and easy to use
The high-quality glass sits in a sturdy aluminum mount. You simply screw it into your 2″ eyepiece or camera adapter. No fuss, just look and enjoy.
What we recommend
✓ Hydrogen nebulae (HII): excellent fit
✓ Emission nebulae: well visible, contrast increased
✓ Deep-sky (H-alpha objects): details clearly visible
✗ Galaxies: not suitable
✗ Reflection nebulae: not suitable
