Now beaming softly
at 5th magnitude in the extreme morning sky, this comet was scarcely
10 degrees up against a brightening sunrise twilight when this
shot was taken. This 3 degree field shows the comets tail to
be of the blue ion type, radiating away from the sun. The head
is a stunning cyan color, with no dust component visible.
The 10d has the
perfect color response for comets. While this image had a very
difficult signal to noise issue with the brightening twilight,
it did well and noise was controllable to usable levels.
