The I-Series Gen2 LRGB filters were designed for cameras containing the Interline KAI11002, KAI16000, sensors. I-Series filters are designed to approximately equalize the flux of Interline CCD detectors (formerly Kodak), including compensation for the solar photon flux. The I-Series filters compensate for the lower red response of these Interline detectors affecting the design of the Green and Red filters. The Luminance and Blue filters are the same as those in our E-Series. 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.
