More About the Astronomik 2" LRGB Filter Set


These filters provide natural color reproduction of planets and stars as well as emission and reflection nebulae. With transmission properties optimized for CCD astrophotography, these Astronomik 2" round, mounted LRGB filters allow acquisition of images in the correct color for all types of objects. Astronomik filters offer the best color reproduction possible. Unlike filters from other brands that have to make unusual compromises. Achieve true color reproduction of stars as well as celestial objects that emit only in spectral lines. Your final images will have perfect colors, as if the objects were bright enough to see in the daylight. This feature represents the fundamental difference between Astronomik filters and filters made by other manufacturers.

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 this 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 these L-RGB filters from Astronomik permit the creation of optimal raw material for sRGB color space image processing.

Astronomik filters are parfocal with wedge errors under all typical margins because of the carrier substrate's high-precision machining. Diffraction limited, these filters will not be the bottleneck in an otherwise high-quality optical system. No longer will you have to worry about focal distance problems or the precise location of the images in each color image! All filters in this set are completely impervious to the impacts of scratching, aging, and high humidity. Each filter arrives with its own long-lasting plastic storage case of superior quality.
