Blood moon and Uranus


Blood moon and Uranus

  2. Colt Musta  The moon is a ball (sphere).  Eclipses happen during full moons, when most stars are not visible due to the light of the moon.  Although much of the sun's light is blocked by the shadow of the moon, a lot of light is still cast onto the moon by the sun shining through the atmosphere around the earth.  Even in eclipse, the exposure on this image tells me that the moon is 64X brighter than a dark night sky.  The exposure I'd use to capture a dark night sky, when you can see a lot of stars, is six stops more sensitive.  So there are stars which would appear behind the moon if I used that sort of exposure (if the ambient light in the sky isn't brighter than them), but they're simply not bright enough to show up at this exposure, in this amount of ambient light.  Uranus apparently is bright enough, so it shows up.
