Unleash the Night Sky's Brilliance with the Antlia Quad Band Anti-Light Pollution Filter

Say goodbye to light pollution and hello to stunning astrophotography with the Antlia Quad Band Anti-Light Pollution Filter. Designed for both color and monochrome cameras, this filter is your gateway to capturing deep sky wonders from the most light-polluted to pristine skies.

Capture the Cosmos in Any Sky The Antlia Quad Band Filter is your ticket to shooting deep sky objects like galaxies, reflection nebulae, emission nebulae, and star clusters across a wide range of sky conditions, from Bortle 8 to Bortle 1. Its spectral transmission spans the visible light region, near-ultraviolet (NUV), and near-infrared (NIR), ensuring your camera's sensor captures the magic of the universe.

Faster Optics, No Problem Designed to accommodate faster optics up to f/2 focal ratios, the Antlia Quad Band Filter is your versatile companion for astrophotography, delivering high-quality results even with rapid optical systems.

Unlock the Power of Near-Infrared Leveraging the high quantum efficiency (QE) characteristics of modern cameras in the near-infrared region, this filter enhances your image's signal-to-noise ratio and contrast. By capturing signals in both visible and NIR bands, it ensures vibrant color balance and simplifies post-processing.

Reveal Hidden Treasures Certain celestial objects, such as M51 and M83, emit significant signals in the near-infrared (NIR) region. With the Antlia Quad Band filter, you can unveil these deep sky gems with enhanced contrast, even in light-polluted skies.

Tailored for Your Camera For cameras equipped with UV/IR cut protective glass, this filter retains visible band transmission while limiting infrared signal capture. However, it truly shines with cameras sporting AR protective glass, enabling the capture of both NIR and visible band signals.
