After several unsuccessful attempts to spot the comet I finally manged to see it naked eye in the morning on July 12th and tonight in the evening. What a great feeling when it grows out of the twilight ... Thanks for all the great imaging and observation reports. I'd like to add my image as captured from the center of Weimar, Germany on July 12th. The image is a stack of 49x15s subs (Pentax DSLR, 135mm lens). It has been stacked on stars, so there is slight bluring of the comet due to its motion. Contrast has been stretched very much to enhance tail structure. I'am wondering about the reddish tail component just at left side of the blue ion tail. Any thoughts about its nature? Anybody else seeing this? I have done some short exposure imaging of the comets head (but f=620mm only), but this has yet to be processed. Anyway I'm happy to share the results later on. Enjoy this beautiful comet!
