    Astrodon - Tru-Balance E-Series - 50mm Square CRGB Filter

    What really distinguishes E-Series Tru-Balance filters is their ability to regulate the transition of photons. Within 10%, the RGB color combine weights are about 1:1:1 which means the observor must only take one dark for equal time multiple expores for RGB.

  7. Astrodon - Tru-Balance E-Series Filters

    Astrodon - Tru-Balance E-Series Filters

    Astrodon Tru-Balance RGB filters have revolutionized CCD imaging. Their popularity is due to ease-of-use, high optical throughput and great resulting color for galaxies, star clusters and nebulae.  There are two varieties of Tru-Balance filters - E-Series and I-Series.

    E-Series filters are designed to approximately equalize the flux of Kodak's full-frame (E-Series) CCD detectors, including compensation for the solar photon flux. This means that your RGB color combine weights will be approximately 1:1:1 within perhaps 10%.  This can never be perfect, but it does allow you to take equal time exposures for your RGB data and also just one corresponding dark exposure time.
