Key Features
The UHC filter selectively reduces specific wavelengths of light, especially from artificial sources, enhancing the contrast of emission nebulae and making them more visible even in light-polluted skies.
Perfect for observing nebulae from urban or suburban environments, this filter darkens the sky background and increases the visibility of deep-sky objects, providing better contrast against light pollution.
Known for its ability to produce exceptionally sharp and clear images, the UHC filter is one of the most popular accessories for astronomers, enhancing both visual observations and astrophotography.
With a 1.25-inch barrel diameter, the filter easily attaches to most 1.25" eyepieces and accessories, making it a versatile addition to your setup. It’s packaged in a sturdy, transparent case for easy storage.
Featuring a high-quality optical glass lens and a durable aluminum frame, the filter is built to withstand frequent use, significantly reducing light pollution for clearer views during both city and suburban observations.
