I had a quick answer from Terry Platt at SX about the green star issue. What he said doesn't entirely make sense to me and I've written back to him for clarification. He essentially wrote that the CCD is most sensitive to red (I question this as I'm pretty sure it is most sensitive to green). He said that red is saturating first due to increased sensitivity and that one sees blue or green as they are not saturated. I cannot figure this out unless what he possibly meant to say is that green is saturating first and the R and B are not. To me this would create a green tinge. Am I missing something obvious?
