The Antlia LRGB-V Pro series filters are designed for monochrome cameras that use both CCD and CMOS sensors. Suitable sensors include KAF/KAI sensors, Sony IMX sensors, GSENSE and other sensor manufacturers. The LRGB-V Pro set is designed to approximately equalize the RGB response from the flux of red-sensitive CCD detectors. The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced imaging time. New LRGB-V Pro series filters feature a carefully designed spectral gap between the green and red channels to minimize the effect of light pollution and to provide high transmittance of useful frequencies. The filters’ design maximizes the capture of details from fainter galaxies and nebulae emissions. The LRGB-V Pro 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 improving the blue channel overflow (haloing) around the star due to B channel overexposure. Antlia LRGB-V Pro series filters block the emission line around 589nm by the design of wide gap between G and R filters, 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 Antlia filters.
Highlight of LRGB-V Pro series set
1. Premium coating technology and finely polished substrate Our quality selection processes are optimized to ensure highly homogeneous glass-substrates. Our application of advanced optical coating technology and double-sided precision polishing achieves both consistent parfocal and optical performance across all filters. 2. Maximized colour balance and contrast for each of the three RGB channels and excellent S/N performance Dozens of coating layers are deposited on both sides of the glass substrate that enables LRGB-V Pro filters to achieve a high SNR. The Anti reflection coatings and carefully designed spectral gaps minimize unwanted light scatter and maximize useful signal data for each filter channel.
3. Tighter star profiles and halo reduction The cut-off rate of LRGB-V Pro series set is designed in high level to minimize halos around brighter stars and reduce star bloat. Our careful design of the blue channel transmission characteristics targets the problem of blue star bloating.
Application and Performance:
1. Designed for monochrome CCD and CMOS cameras
2. Great imaging colors for celestial objects, galaxies, star clusters and nebulae
3. AR anti-reflection film design for secondary reflection and star halo reduction
4. R-Filter provides maximum transmission of H-alpha and S II emission
5. B/G overlap doubles the energy in the OIII line
6. Balanced RGB-design offer 1:1:1 exposure times for most telescope optical systems
7. All Antlia LRGB-V Pro filters are edge blackened to eliminate internal reflections from stray light
8. The substrate thickness of each of the four LRGB filers is maintained to tight tolerances
9. Not recommended for Solar observing and imaging
10. Not recommended for visual observation
Important Note: When using any parfocal filters, the user may still experience focus shifts between filters during long imaging sessions. It is important to remember that temperature shifts will change the length of the optical path due to the differential contraction between the telescope tube and the glass optical elements. It is recommended that the photographers check focus either manually or automatically in software every 1 to 2 hours. In cases where the telescope has been brought from a warm environment to outside, more frequent focus checks are required until the equipment has stabilized nearer to ambient temperature.

The transmission properties of the L-RGB Filterset 1.25in Type 2c filters are optimized for CCD astrophotography. The set allows taking images in correct colours for all types of objects. Where other brands make strange compromises, we do the best colour reproduction possible. Both stars as well as objects that emit only in spectral lines, are reproduced in their true colors. You get CCD images with perfect colours, as if the objects where bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters an those of other manufacturers.
The following aspects have been most important for the design of our filters:
- simple image processing for the user
- highest transmission (nearly 100%) for short exposure times
- adjusted transmissions of the individual filters for optimal colour reproduction
- the use of industry standards
Astronomik doesn't stop thinking at the step of taking the picture. More important a tool should be given to the astrophotographers that offers a simple and elegant editing process. To maintain the colour, we calculated our filterset for the sRGB color space, that is used as an industry standard from most manufacturers of monitors, printers and imaging software. As a user, you do not need to spend time learning about colourimetry and colour spaces. We have solved the special problems of astrophotography for you.
Due to the high-precision machining of the carrier substrate, our filters are parfocal with wedge errors below all usual margins. In order not to be the bottleneck in a high-quality optical system Astronomik filters are of course diffraction limited. Issues concerning focal distances as well as the exact location of the images of each colour image are not a problem at all!
Main use
The L-RGB filter set divides the spectrum into its components red, green, blue and luminance. Thus colour separation can be achieved with pure b/w CCD sensors. The separation corresponds to the colour sensitivity of the human eye according to DIN 5032. By using the sRGB color space it is possible to maintain the color of the image throughout the entire image processing and output. With an Astronomik L-RGB filter set and your camera you create ideal raw material for image processing in the sRGB color space.
