Omegon Nebula and City Light Filter 1.25″

Omegon Nebula and City Light Filter 1.25″ is designed for observers who still want to see nebulae from urban or suburban areas. Artificial lighting is often the biggest enemy of detail in deep-sky observation. This filter addresses exactly that problem by effectively suppressing distracting light sources - such as sodium- and mercury-based street lights.

Unlike extremely narrow-band UHC or OIII filters, this filter allows a slightly wider portion of the spectrum to pass through. This keeps the image natural and bright, but significantly improves the contrast of emission nebulae, planetary nebulae and other diffuse objects. The filter allows transmission lines of H-beta and OIII light through, while filtering out unnecessary wavelengths. So you get a darker background sky with improved visibility of structures and edges within nebulae.

Its standard 1.25″ mount makes it instantly compatible with virtually any eyepiece. Ideal for telescopes between 100 and 200 mm, and a popular choice for anyone who wants to see more without traveling to a dark observing site.

Advantages
✓ Specially designed for light-polluted urban areas
✓ Visibly increases contrast in emission nebulae and star clouds
✓ Blocks light from street lights, allows useful haze light through
✓ Natural-looking image thanks to wideband transmission
✓ Fits any 1.25″ eyepiece - ready to use immediately

Application
The Omegon Nebula and City Light Filter 1.25″ is perfect for visual observation of bright deep-sky objects from light-polluted locations.
