More About Astronomik 2" LRGB Filters
For pure color facsimiles of planets, stars, emission nebulae, and reflection nebulae, Astronomik 2" round, mounted LRGB filters are tough to beat. Featuring transmission properties enhanced for CCD imaging, these filters allow the procurement of correct color images for a wide range of objects. Unlike filters from other brands that make bizarre compromises, Astronomik filters offer the greatest possible color facsimile. You'll see stars as well as objects that only emit in spectral lines in their true colors. The color in your resulting images will be so flawless, it will be as if the objects were bright enough to see with the sun out. This is what differentiates Astronomik filters from filters other manufacturers have developed.Astronomik doesn't end their thought process at the picture taking step. They know astrophotographers want an instrument that enables a simple, elegant editing process. For color retention, Astronomik has figured their LRGB filter set for the sRGB color space, a well-established industry standard for most makers of monitors, printers, and imaging software. The spectrum is split into its four components: red, green, blue, and luminance. This allows color separation to be achieved with pure black & white CCD sensors. This separation correlates to the color sensitivity of the human eye per DIN 5032. By utilizing the sRGB color space, there will be no reduction in the color during the entire processing and output of the image. The combination of your CCD camera and Astronomik's L-RGB filters allows the creation of optimal raw material for sRGB color space image processing. The high-precision machining of the carrier substrate on Astronomik LRGB filters makes them parfocal with wedge errors under all customary margins. Diffraction limited, these filters will not reduce the superior quality of your optical system. Focal distance issues as well as concerns about the exact image location in each color image are no longer applicable! These filters also provide full resistance to scratching, aging, and high humidity. Durable, high-quality plastic storage cases are included with all Astronomik LRGB filters.
