Discovered by Robert McNaught on May 20, 2005, this comet’s 7.1 year period brought it back to a September 12th perihelion.  The comet is now outbound, about to cross the orbit of Mars and viewable in the constellation Andromeda.

This image was taken on the evening of September 13th.  It is a stack of 45 sixty second exposures all aligned to the comet.  This is one of the few images of comets that I have taken that shows some structure in the tail.
