This image shows the comet in the constellation of LEO as it moves through the solar system. The data for this image were obtained in the morning hours of an observing run on the WIYN 3.5 m telescope lead by graduate students of the Department of Astronomy at the University of Wisconsin.
The bright, unresolved nucleus of the comet as well as its diffuse, blueish coma and long tail are easily visible. As the telescope was following the comets movement relative the the background star-field, stars became elongated, and repeated observations with different filters created a caleidoscope of colors. Two satellites crossed the path of the comet during the exposure and are visible as green and red streaks, adding to the starry firework.
