ANTLIA ULTRA NARROWBAND

 

Antlia Ultra narrowband filters for astrophotography with monochrome CCD and CMOS cameras boost the contrast of emission nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution. 

The strict manufacturing process and the quality control guarantees a tight tolerance of the filter thickness (± 0.05mm) which makes these filters parfocal. This allows the filter change without the need to refocus. Each filter is fully multi-coated to minimise internal reflections, halos around stars and to assure a high transmission which is above 90%. To even further enhance the contrast, reduce the glare and internal reflections, Antlia applies edge-blackening coating on each filter.

Antlia filters are available in 1.25" and 2" mounted or 36mm and 50mm unmounted varieties.
