Lumicon 1.25" Deep Sky Nebular Visual Filter & Galaxies.
The best all-purpose nebula filter on the market today, the Lumicon 2in Deep Sky Filter blocks all high & low pressure mercury and sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum. Visually, the Deep Sky Filter enhances contrast of nebula under both light-polluted and dark skies. The Deep Sky Filter also passes infrared light, making it an excellent filter for photographing most deep space objects through light-polluted skies.
