As far as an astral photo was concerned
the first thing I thought of was the moon.
However, the moon is considered to be
a dead rock that only reflects the sun.
It does have an astral body
but life left it a long time ago.
My Nikon D90 captured this image
using a Sigma 50-500mm lens
Focal length: 500mm
My spelling of ‘apperture’ is considered
to be archaic by Wiktionary,
while other web-based spell checkers
are happy with the double ‘p’.
