Astrophoto Home Page | Home Page  


On this evening, Comet C/2006 M4 (SWAN) was in the constellation Hercules, passing not far from globular cluster M13. Unfortunately a nearly 1st quarter moon decreased contrast enough that visually the tail of the comet was just barely detectable. Fortunately, with a lot of contrast enhancement applied to the photo, it can be seen to stretch across the central part of the constellation.
