More About Astronomik 31 mm LRGB Filters
For pure color facsimiles of planets, stars, emission nebulae, and reflection nebulae, Astronomik 31 mm round 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.The act of capturing the image is not the end of the thought process for Astronomik. They know astrophotographers desire a tool that will make editing an easy, uncomplicated procedure. To maintain the color in an image, Astronomik has figured their LRGB filters for the sRGB color space, a well-known industry standard for producers of monitors, printers, and imaging software. The spectrum is separated into red, green, blue, and luminance components, allowing the possibility of color separation with true black & white CCD sensors. According to DIN 5032, this separation correlates to the color sensitivity of the human eye. Using the sRGB color space enables the color of the image to be maintained throughout its full processing and output. Combining your CCD camera with this LRGB filter set from Astronomik provides the ideal raw material needed 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 Focal distance issues as well as concerns about the exact image location in each color image are no longer applicable!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.
