Antlia ALP-T 36 mm Dual Band Narrow Band Nebula Filter - 5 nm

Antlia ALP-T Dual Band 5 nm Narrow Band Nebula Filter for B/W and Color Cameras

Antlia designed this 5 nm dual line-pass filter for one-shot color cameras (OSC), DSLRs and mirrorless system cameras. However, it can also be used as a narrow-band filter for mono cameras to save valuable shooting time and produce extremely high-contrast luminance shots, even in moonlight and near cities.

The ALP-T dual-band filter passes red H-alpha light (656.3 nm) and green O-III light (500.7 nm) and blocks all other wavelengths. In particular, the unwanted wavelengths of light pollution and airglow are blocked. This allows you to take deep deep sky images even in moonlight and from close to the city. The signal-to-noise ratio is greatly increased, allowing you to bring out even the faintest nebulae.

The quality features of Antlia narrow band filters at a glance:

High light transmission and smallest bandwidth to maximize contrast.

Steep spectral profile minimizes halos around bright stars

Single substrate to eliminate internal reflections

Usable in light-polluted areas and dark locations

Extends exposure time in moonlight conditions

Antlia narrowband Pro filters can be used with low signal loss down to f/3 systems

All Antlia narrowband filters are blackened at the edges to prevent internal reflections of stray light

Superior optical reliability reduces image post-processing effort
