Omegon Pro H-Alpha Filter 7nm (1.25 inches)

Omegon Pro H-Alpha 7 nm Filter - Astrophotography of hydrogen nebulae even in the middle of the city
Young stars glowing in deep red nebula light: the Omegon Pro H-Alpha 7 nm filter lets you capture hydrogen nebulae with impressive detail. Thanks to the very narrow pass of only 7 nanometers, you get extremely high contrast, even under light-polluted skies. This allows you to take astrophotos you can be proud of, even from urban areas.

Maximum contrast for serious astrophotographers
This filter allows only H-alpha light to pass through and blocks virtually all other wavelengths. Artificial light from sodium and mercury vapor lamps is effectively suppressed. Compared to a 12 nm filter, you will see significantly more contrast and finer structures in nebulae. Less background light means more detail in your image.

Designed for advanced astrophotography
The Omegon Pro H-Alpha 7 nm filter is perfect for astro cameras and custom DSLR cameras. Its interference technology with ultra-thin layers ensures sharp, high-contrast images. Whether shooting in the city or under dark skies, this filter gets the most out of your data.

What we recommend
✓ Hydrogen nebulae: ideal for maximum detail
✓ Astrophotography: perfect for narrow-band shots
✓ Light-polluted locations: highly effective
✗ Visual observation: not appropriate
✗ Planetary nebulae and comets: limited usefulness
