Antlia LRGB V-series astronomy imaging filters

Description

The Antlia LRGB V-series filters are designed for monochrome cameras that use both CCD and CMOS sensors. Suitable sensors include KAF/KAI, Sony, GSENSE and other sensor manufacturers. This filter set is designed to approximately equalize the RGB response from monochrome sensors.   The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced dark frame library.


LRGB V-series filters highlight both the spectral gap design between green and red filters to minimize effect of light


pollution and high transmittance of useful emission lines which means it remains effective for weaker emission lines from galaxies and nebulae. The V-series filters guarantee the high transmission of the OIII band in both the B and G filters


(OIII signal >95% in blue and green).


The Antlia V-series filters block the emission line around 589nm, which suppresses much of the light pollution from high


pressure sodium and mercury street lamps and results in a more natural color balance.


Application and Performance:

Designed for monochrome CCD and CMOS cameras;

Great imaging colors for celestial objects, galaxies, star clusters and nebulae;

Transmittance rate>95%, high optical throughput;

2 sides AR coating, significant reflection and star halo reduction;

RGB color combine 1:1:1, resulting in well balanced RGB and LRGB images;

Equal RGB exposures means one master dark frame;

Parfocal across all filters in this set;

Improved color separation with suppression of mercury and sodium lines.
