Two comets: Comet Holmes and Comet Tuttle

While Comet Holmes is quite large (about 1° in width) it is much fainter than it was two months ago. However, Comet Tuttle is returning to the inner solar system. It's about magnitude 6 and just visible in dark skies. In light polluted city skies it is just barely visible. With a four 30-second exposures stacked and 7 dark frames subtracted I was able to tease out the faint green of Comet Tuttle.

 

On December 30 it will make its way toward the constellation Triangulum and come very close to the Triangulum Galaxy.
