Antlia narrowband filter with 3 nm bandwidth

Antlia nebula filters offer extreme contrast. Thus, the astrophotographer achieves a very good result even with considerable stray light from cities or from the moon. Antlia guarantees a transmission of at least 88% in the 1 nm range around the central passband. This makes the narrowband filters interesting also for fast telescopes and objectives. Even at an extreme focal ratio of f/3, there is only minimal transmission loss.

The quality features of Antlia narrowband filters at a glance:

• High light transmission and narrowest 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 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 post-processing of the image
