    Astrodon LRGB E Series 50mm Square Filter Set - Gen II

    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.

    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.

     

    • Best choice for backthinned and Sony detectors

     

    • Equal RGB exposures and one dark time

     

    • Better color separation (spectra)

     

    • Better color rendition for galaxies based upon color theory

     

    • ignificant reflection and star halo reduction

     

    • Enhanced contrast for HII regions in galaxies

     

    • Spectral "gap" to minimize effect of light pollution

     

    • Highest efficiency blue filter with less UV

     

    • Correct "teal" OIII color for planetary nebula

     

    • More parfocal - thickness 3+/-0.025 mm*

     

    • Parfocal with Astrodon's high-performance narrowband and near-IR filters

     

    • Striae-free 1/4 wave fused silica substrates

     

    • 30 arcsec parallelism

     

    • Ultra-hard and durable sputtered coatings
