This image was taken using a Celestron Comet Catcher (5.5-inch Schmidt-Newtonian x f/3.6 = 20-inch FL) and Hi-SIS-22 CCD camera (Kodak KAF 0400 with 768 x 512, 9-micra pixels), but in 1x1 (full) pixel mode. With this system, the view is about 48 x 32 arcminutes. Exposures were 2 minutes each image begun at 05:11 and 05:23 UT for M57 (Ring Nebula in Lyra) and the Comet, respectively. Though the Comet was speeding on, its broad tail matched sufficiently in both images separated by 12 minutes.
