astronomik - L-RGB Filtersatz Typ 2c 1.25 inch LRGB

The transmission curves of the Astronomik RGB filters are optimized for the CCD-astronomy: With these
filter-set, we finally can offer filters that make color proof pictures of all objects possible. Continuum
radiators like stars and galaxies as well as objects that shine only in single lines (e.g. planetary nebulae),
are reproduced in their true colors. Because of the design of the band pass of the filters, the color
sensitivity of the human eye is optimal reproduced. You get CCD- pictures, that show the object optimal in his
colors, just as if you would see it, if your eye would be sensitive enough. 
The Astronomik Type II filter will permit color pictures without an extra IR- cutoff filter, because each of the three filter will
be blocked near to the infrared (~1150nm). All three filter have the same thickness, so that color images without focusing between
the singular pictures will be possible. They are designed to work with nearly all CCD sensors available on the market. With these
sensors you get pictures with a very good color balance. 

    * Astro- optimized transmission curves for images without color-shifts
    * each filter blocks the IR, no additional filter necessary
    * Correct images as well for very red as for deep blue objects because of reproduction of the eye´s sensitivity
    * Transmission of nearly 100%
    * Same optical thickness of all filters
    * Insensitivity to high humidity, scratches and aging
    * Glass substrate of very high quality: You get the sharpest images your scope can deliver
