Explanation:
Comet
C/2001 A2 (LINEAR) has crossed the celestial equator and is
heading north.
Outward bound,
this primordial
piece of the solar system is still
just visible to the unaided eye and can now be sighted by northern
hemisphere skygazers as it moves
through
the constellation Pisces.
This
picture of the comet is a combination of 33 individual one minute
exposures made on June 30 with a small telescope and
digital camera situated in central Arizona, USA.
The composite image brings out faint details
in the comet's tail which
was
reported to extend for several degrees,
beyond the camera's roughly 2 degree field of view.
Closely spaced, the combined exposures were registered on the
comet so background stars appear trailed.
To produce the "punctuation" at the end of each
star trail, two exposures
near the end of the sequence were left out.
As a result, the final dots nicely reveal the pattern of the
background star field.
