Here is battery one part two where I held stationary and watched the light change. This is 1920 x 1080 at 60 frames uploaded directly to YouTube from QuickTime.
What I like best in this video, is the demonstration of significantly improved dynamic range of the C23 vs the CGO3+... this video with the CGO3 would be a dark muddled mass of blocky mush. With the C23 you can right from the start, distinguish streetlights and the roofs of the houses.
