Thank you!Excellent!! Is the last one in the shadow of the eclipse?
Yes - the last one is the eclipse close to it’s maximum. Only the very top is lit by the sun - the rest is in earth’s shadow. Which, interestingly enough, is why it’s red - that part of the moon is lit by light rays that pass through earth’s atmosphere, which scatters red & violet wavelengths but passes red and orange. And those wavelengths are refracted or bent as they pass through the atmosphere, which is why they reach the moon even though it is in earth’s shadow.
Y’all may already know all that, but somebody asked me that question - why is it red? - when I was photographing it, and I didn’t have the full answer right then & there. So now I do.
