Antlia Highspeed Narrowband Filter with 3 nm Bandwidth

Nebula filters from Antlia offer extreme contrast. This allows the astrophotographer to achieve a very good result even with considerable stray light from cities or from the moon.

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

Use in light-polluted areas and dark locations

Extends imaging time in moonlight conditions

Antlia Highspeed filters are optimized for systems with f/2.6 to f/3.6 focal ratio

Transmission is at least 90%

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

Superior optical reliability reduces the time and effort required for post-processing of images
