Omegon Nebula and City Light Filter 1.25 inch

Omegon Nebula and City Light Filter 1.25 inch: more contrast under a city sky

Artificial light is the greatest enemy of deep-sky observation. This broadband filter suppresses the wavelengths of sodium and mercury lighting, making the background of the sky darker and helping nebulae stand out better from that gray glow.

The filter allows a broader portion of the spectrum to pass through than a UHC or OIII filter. As a result, the image retains its natural colors and brightness, while the contrast of emission nebulae and planetary nebulae is enhanced. For those observing from the city or the outskirts of a village, this is the most affordable way to upgrade.

Features

• Broadband rejection filter for sodium and mercury lighting
• Passes the OIII and H-beta lines, keeping nebulae visible
• Retains natural star colors, no strong color cast
• Standard 1.25 inch thread

Compatibility

Screws onto the filter thread of any standard 1.25-inch eyepiece. Works starting from an aperture of about 80 mm; the larger the aperture, the more pronounced the effect.
