ANTLIA

Testar is the authorized distributor for Antlia in Australia. Antlia produces high quality LRGB, narrowband and planetary filters for astrophotography with monochrome CCD and CMOS cameras. 

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 31mm, 36mm and 50mm unmounted varieties.
