This image was made with 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) in 2x2 bin mode. With this system, the view is about 48 x 32 arcminutes. Exposure was 2 minutes begun at 0438 UT. Significant movement is obvious in adjacent images taken only a few minutes apart. The comet was located somewhat symmetrically across from M13 near Zeta Herculis in the western side of the Keystone of Hercules.
The sky was very transparent with virtually no humidity, temperature 64-58F, and only occasional, high cloud intruders. I found Comet S-W3 with the 12.5-inch x f/6 Newt at 75x, estimated its tail more than half degree visually. This surely is the major C component.
