Classic Lumicon 1.25 Inch Oxygen III Filter helps faint objects become much more visible against the blackened background of space. Lumicon 1.25 Inch Oxygen III Filter visually isolates the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae. New Price: $50

Lumicon 1.25 Inch Deep Sky Filter is the best all-purpose nebula filter on the market today.  It blocks all high & low pressure mercury and sodium vapor lamp light, neon lights and air glow, while transmitting the rest of the visible spectrum.

Visually, Lumicon 1.25 Inch Deep Sky Filter enhances contrast of nebula under both light-polluted and dark skies and also passes infrared light, making it an excellent filter for photographing most deep space objects through light-polluted skies. New Price: $100

Lumicon 1.25 Inch Hydrogen-Beta Filter is also known as the Horsehead Nebula filter.  This filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9nm wide, providing maximum contrast.

Aids in viewing of extremely faint nebulous objects such as the Horsehead, Cocoon and California Nebulae. In many cases, the Lumicon Hydrogen-Beta Filter is the ONLY way to view these objects. Recommended for 8″ or larger telescopes. New Price: $100
