ANTLIA 4.5nm EDGE NARROWBAND FILTERS

(4 products)

 

Testar is the authorized distributor for Antlia in Australia. The Antlia 4.5nm Edge narrowband filters have the same excellent transmittance characteristics as their 3nm Pro series but at a more affordable price.

The 4.5 nm bandpass is only 1.5% of the entire visible spectrum, increasing the signal to noise ratio and delivering high contrast images and extremely dark backgrounds. Available in 1.25", 2", 31mm, 36mm & 50mm round.
