Explanation:
Ranging throughout the
solar system, these pictures all
have something in common.
They were taken with an 8 inch diameter telescope, a size popular
with amateur astronomy buffs, and slightly modified "web cam"
of the type widely used to send images out over the internet.
The results are clearly
remarkable
for such inexpensive and readily available equipment.
Each sharp image was produced from 20 to 30 frames which
were digitally stacked and processed using
free software.
Until recently, digital imaging for amateur astronomers required a
specialized camera,
but the advent of low-light
video surveillance cameras and web cams now presents other
options for
relatively
bright solar system objects.
Want to try some
unconventional
web cam astronomy?
Geoff Chester, Public Affairs Officer at the
U.S. Naval Observatory,
offers these images and an
account
of his own adventures
from a suburban front lawn near Washington D.C.
