One Night, One Telescope, One Camera
Taken on the same night, from the same place, with the same telescope
and camera, these postcards from our
Solar System are shown at
the same scale to provide an
interesting comparison of apparent sizes.
Spanning about
half a degree in planet Earth's sky, the Moon
is a stitched mosaic of six images.
The others are the result of digitally stacked frames or
simple single exposures, with the real
distances to
the objects indicated along the bottom of each insert.
Most of the Solar System's planets with their brighter moons, and Pluto
were captured during the telescopic expedition,
but elusive Mercury was missed because of clouds near the horizon.
The International Space Station
was successfully hunted, though.
The night was July 21st.
Telescope and camera were located at the
Centro Astronomico de Tiedra
Observatory in Spain.
