Omegon Pro UHC Nebula Filter 1.25″

Omegon Pro UHC Nebula Filter 1.25″ is a powerful tool for deep-sky observers who want to see more detail in nebulae, especially under polluted skies. UHC stands for Ultra High Contrast - and that's exactly what you get. This narrow-band filter lets only specific wavelengths through (especially OIII and H-beta), while almost completely suppressing distracting city light.

This selective transmission turns the sky background deep black, while emission nebulae light up with more structure and contrast. You will discover details in nebulae that are barely visible without the filter - think filaments in the Veil Nebula or the edges of the Lagoon Nebula. This filter also provides extra contrast for dark locations.

The filter fits any 1.25″ eyepiece and is suitable for telescopes from about 100 mm aperture. Thanks to high-quality coating technology, reflection is minimized and the image remains color-neutral in the transmitted bands.

Advantages
✓ Increases contrast of emission nebulae dramatically
✓ Blocks almost all interfering artificial lighting
✓ Allows only the light from OIII and H-beta to pass through
✓ For observations in city as well as dark locations
✓ Fits any 1.25″ eyepiece - ready to use immediately

Application
The Omegon Pro UHC Nebula Filter 1.25″ is ideal for observers who want to study emission nebulae from light-polluted areas. The Orion Nebula, Veil Nebula and North America Nebula become more clearly delineated. Especially when used with Newton or refractor telescopes from 100 mm and up, you achieve the maximum effect. Perfect for the serious deep-sky enthusiast.
