Antlia: Ultra-Narrowband Filters for Deep-Sky Astrophotography

Antlia is a Chinese brand specialising in the production of high-precision astronomical filters for deep-sky imaging. Born from a community of professional and enthusiast astrophotographers, Antlia stands out for its ultra-narrow passbands — among the most selective available on the market — with transmission curves measured and certified for each production batch. Antlia filters are designed to maximise the contrast of emission nebulae even from the most light-polluted skies, compatible with any mono or colour CMOS camera.

Mono-Band, L-RGB, Dual Band and Triband for Every Setup

The Antlia range covers all the main requirements of narrowband astrophotography. The mono-band H-Alpha, OIII and SII filters with passbands of 3 and 3.5 nm ensure near-total isolation of nebular emission lines, eliminating stellar continuum and light pollution — ideal for HOO and SHO imaging (Hubble palette) with mono cameras. The dual-band and triband filters allow capture of multiple emission lines in a single exposure, making them the ideal solution for OSC colour cameras. The L-RGB sets complete the kit for colour imaging with monochrome cameras. Filters are available in the most common formats for telescopes and astronomical cameras.
