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. 

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.
