Explanation:
Have you seen the Moon lately?
On April 18, its waxing sunlit crescent moved through planet Earth's
night across a background of stars
in the Hyades.
Anchored by bright star Aldebaran, the nearby, V-shaped star cluster
and complete lunar orb appear in this telephoto image.
The engaging
skyview is actually digitally composed from a series of
varying exposures.
Recorded in 1/60th of a second, the shortest in the
series captures the Moon's bright crescent in sharp detail.
Longer exposures, ranging up to 15 seconds,
capture fainter background stars as well as
earthshine,
visible to the eye as the earthlit
lunar
night side.
