ASTRODON E Series Gen 2 Tru-Balance LRGB 1.25” Filters – NEW

$400 Posted

Astrodon LRGB Gen2 E-Series Tru-Balance filters have revolutionized CCD imaging. Their popularity is due to their ease-of-use, high optical throughput and great resulting colors for galaxies, star clusters and nebulae.

E-Series filters are designed to approximately equalize the flux of red-sensitive full-frame (formerly Kodak 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% for equal length exposures. *This can never be perfect, but it does allow you to take one exposure time for all of your RGB data and therefore, only just one corresponding dark exposure time. *Again, this saves you precious imaging time and thus, simplifies your imaging.
