Lumicon Night Sky Hydrogen-Alpha 48mm Filter |
The Lumicon Night Sky Hydrogen-Alpha 2" Filter can help reduce the effects of minimal pollution/haze when it comes to shooting deep-sky images. In black and white photography, maximum contrast can be accomplished resulting in dense backgrounds which, for celestial photography, can only enhance an image. For planetary observing, color filters ...

Lumicon Comet Filter 48mm Filter |
The Lumicon 2" Comet Filter, a narrow band-pass filter (25nm), isolates the 501nm OIII line and both C2 lines at 511nm and 514nm. The high contrast of the filter reveals the delicate ionized tail of gaseous comets, allowing you to see their full extent. The Comet Filter also helps you to better distinguish gaseous comets from dusty comets, wh...

Lumicon Hydrogen-Beta Filter |
Also known as the Horsehead Nebula filter, the Lumicon Cassegrain Hydrogen-Beta Filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide, providing maximum contrast. The Cassegrain filter-cell threads onto your telescope's SCT rear-cell, and presents male SCT threads for accessory attachment. Lumicon...

Lumicon Hydrogen-Beta Filter 1.25" |
The Lumicon 1.25" Hydrogen-Beta Filter exclusively isolates the 9 nm-wide hydrogen-beta line of the light spectrum (486nm), to provide the maximum possible contrast on very faint nebulae. You won't be able to find the celestial objects with the filter in place because it lets so little light pass, you would instead locate them and ...

Lumicon Oxygen III Filter |
The legendary Lumicon Cassegrain Oxygen III Rear Cell narrow band-pass filter threads onto your telescope's SCT rear-cell, and presents male SCT threads for accessory attachment. Lumicon knows that all sky viewing is not done under the best of weather conditions. The Cassegrain filter cell allows you to change eyepieces without threading/unthreadi...

Lumicon Oxygen III 48mm Filter |
The legendary Lumicon 2" Oxygen III Narrow Band-Pass Filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae. Lumicon has designed a filter that enables these distant objects to be clearly seen. The 1.25" filters employ industry-standard 1.125" x 42 tpi...

Lumicon Ultra High Contrast 1.25" Filter |
The original Lumicon 1.25" Ultra High Contrast Filter is unbeatable for revealing nebulosity. This is achieved by passing three nebula emission lines-the two doubly ionized oxygen lines (496 and 501nm) and the H-beta line (486nm)-while blocking light-pollution and Sky Glow. The result is superb views of the Orion, Lagoon, Swan and other extended n...
