Astronomik 1.25" Round Mounted Green Filter

  • This green Astronomik Type 2c filter with close to 100% transmission is mounted in a round 1.25" cell
  • The effects of scratching, aging, and high humidity are negated by this filter's coatings
  • Diffraction limited, this filter will not compromise your telescope system's optical performance
  • Astronomik has adjusted this filter's transmission for color reproduction that is optimally suited for simple image processing
  • Extremely short exposure times are enabled by higher transmission
  • Because this 1.25" Green Filter already blocks Infrared, a supplemental IR blocking filter is not needed
  • Made in Germany, a country known for producing optics of superior quality!

More About Astronomik 1.25" LRGB Filters

With transmission properties ideal for CCD astrophotography, Astronomik 1.25" round, mounted LRGB filters enable pure color reproductions of all sorts of objects, including planets and stars as well as emission and reflection nebulae. While filters from other brands have to make unusual compromises, these Astronomik filters offer the finest color reproduction possible. Stars as well as objects that only emit in spectral lines will be seen in their true colors. In fact your images will have such flawless colors, it'll be as if the featured objects were bright enough to see in the daytime. This represents the fundamental difference between Astronomik filters and filters from 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 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.

Due to the high-precision machining of the carrier substrate, Astronomik filters are parfocal with wedge errors below all usual margins. Astronomik filters are diffraction limited to keep them from being the weak link in an otherwise high-quality optical system. Focal distance problems as well as the precise location of the images in each color image are no longer concerns! These filters also offer total resistance to scratching, high humidity, and the effects of aging. Each filter comes with its own high-quality, long-lasting plastic storage box.
