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
