Not saying you're wrong about the eye adapting, but note that Collins was not a moonwalking astronaut. I've considered that this could be some difference between viewing the solar corona from the command module as opposed to the surface. It could also be memory issues. Perhaps they ran so many drills with a simulated solar corona photographing sequence that the guy who stayed in the sky mixed up this experience and the real thing, whereas Armstrong knew what it actually looked like. I've entertained wilder thoughts as well, but on the whole I think there's probably a mundane, down-to-moon explanation for the disagreement and elbow nudge.
