Celestron's Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sod... [more]
The best light pollution filter on the market today. Blocks all high & low pressure mercury and sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum. Excellent for both visual and photographic applic... [more]
The ULTIMATE nebula filter. The original Lumicon 1.25in 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 (... [more]
The legendary LUMICON OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae. Thus, these faint objects become much more visible against the blacken... [more]
The Horsehead Nebula filter. The Lumicon H-Beta Filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide. The result is extreme contrast between the black background of space and the delicate Hydrogen - B... [more]
The Lumicon Comet Filter, a narrow bandpass system (25nm), isolates the 501nm OIII line and both Cyanogen lines at 511nm and 514nm. The high contrast gain of the filter reveals the delicate ionized tail of gaseous comets, allowing you to see their full... [more]
The Night Sky Hydrogen-Alpha Filter is intended for deep sky astrophotography only.
WARNING: DO NOT USE FOR SOLAR OBSERVATION, EYE DAMAGE MAY OCCUR.
The Lumicon Night-Sky H-Alpha Filter is a powerful photographic aid in overcoming ligh... [more]
We are pleased to announce the beginning of a new line of filters, with the traditional Tele Vue attributes of highest optical quality and 100% quality control. The first model available will be the Tele Vue Bandmate OIII, followed by a UHC model. All ... [more]
