While Coyotes howled at the celestial Hare, Lepus, above the SW horizon, I was able to make four images of Comet Lulin. In the first two images, you can see a few geosynchronous satellites as they appear to shift position eastward as the mounting tracks the comet and stars westward. A close look at the last two images will reveal several distant galaxies. Comet Lulin's ion tail is nearly non-existent. Lulin was quite easy to spot with the naked eye and averted vision when only 20 degrees above the ESE horizon. The brightest star in the first three images is Porrima (Gamma Virginis). In the first two images, the second brightest star at the top, directly above the comet, is Zaniah (Eta Virginis), and the orange star to its left is the variable star SS Virginis. Canon Rebel XTi with 85, 135, and 300 mm Nikkor lenses @ f/2.8, 3, and 4.5 respectively. Exposures range from 2 to 4 minutes at ISO's 800 and 1600.
