Comet Bootes
Uploaded 10/22/06
Now visible
to the naked eye and rising higher every evening, Comet Swan
was a splendid target for imaging from our vantage point on the
top of the Colorado Plateau. The tail was faintly visible in
the 11x80 binoculars, and seen here shows a long bluish ion tail
and a short fan like dust tail right near the greenish coma.
This image was tracked on the nucleus, and left short star trails,
which is the movement the comet would have blurred if I had tracked
on the stars. The comet is moving fast, and even in 40 minutes,
the comet moved over 10 arcminutes. Eight exposures of 5 mins
each were averaged for this image to retain the core detail. |
