LRGB-V Pro Antlia Filter Set 1.25inch
More about the product
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.
The 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 bandwidth of the B channel is narrowed for the purpose of
effectively improving the blue overflow around the star due to B channel
overexposure when RGB is synthesized.
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. The
uniformity in substrate thickness delivers good parfocal performance
across all of its narrowband filters.
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.
