There have been
few comets as strongly colored as this one. The intense Swan
Bands in the spectrum of this object put forth a very strong
fluorescent green coloration to the comets coma. The image on
the left is 11 minutes of exposures stretched to match the appearance
in the eyepiece. This is a full resolution image with the ST8I.
The image on the right is a color separate image, combined from
RGB data. More details are with each image sub page. The comet
is currently 8th magnitude in Pegasus.
