Description
Antlia ALP-T Dual Band 5 nm Narrow Band Nebula Filter for black and white and color cameras
Antlia designed this 5nm dual line-pass filter for one-shot color cameras (OSC), DSLRs and mirrorless system cameras. However, it can also be used as a narrowband filter for monochrome cameras to save valuable shooting time and produce ultra-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, unwanted wavelengths of light pollution and air glare 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 significantly increased, allowing even the faintest nebulae to emerge.
The quality characteristics of Antlia narrowband filters at a glance:
♦ High light transmission and minimum bandwidth to maximize contrast.
♦ Steep spectral profile minimizes halos around stars bright
♦ Single substrate to eliminate reflections
♦ Indoors Can be used in light-polluted areas and places dark
♦ Extend exposure time under conditions of moonlight
♦ Antlia Pro narrowband filters can be used with low signal loss up to systems f/3
♦ All Antlia narrowband filters are blackened at the edges to avoid internal reflections of light widespread
♦ Superior optical reliability reduces image post-processing effort
