# The total lunar eclipse of 2025 March 14 at mid-totality (06:58:44 UTC), seen through
|
|
# a 400 mm lens from 7000 km out on the line from Earth's center to the Moon. Needs the
|
|
# astrokit feature and its kernels.

# At lighting L1 the Moon is inside Earth's shadow, lit only by the sunlight Earth's
|
|
# atmosphere bends into it, dim and red, and brightest along its northern edge, farthest
|
|
# from the shadow's axis. The exposure, 0.3 s, is 3000 times the example camera's, as a
|
|
# photograph of totality would be. At L0 the Moon is drawn without Earth's shadow, as a
|
|
# full Moon, thousands of times brighter, so L0 takes its own exposure of 1 ms.
