Comet Garradd passing along (August 2nd ) through the Bar Galaxy PGC67040. Two other smaller galaxies (mid tail area) are also shown in this region.
A 56 minute time lapse animation was done showing its movement and at approaximately magnitude 7.8!.
This short animation is made from 12 individual LRGB frames, 2 min. exp. time in each channel. Taken between 23:32 UT on August 2nd (first frame) and 1:42 UT on August 3rd 2011 (last frame). Due to unstable atmospheric conditions the color and brightness of individual frames vary from frame to frame. Please check also this hi-res Vimeo

Nice animation, Emil! What is the streak that appears to pass through M15?
Thank you very much, Bystander!
The streak is a satellite trace which appears on the luminance subexposure of the frame number 11 of the animation. Here is this sub:

Are you ready for some excitement? How would you like to watch a LIVE broadcast of Comet C2009 P1 Garradd?! Thanks to our good friends at Bareket Observatory and clear skies in Israel, we can do just that! Step inside to our virtual observatory…
Before you get upset and think there’s something wrong, there are a few things you must remember about watching a live telescope broadcast. If there are clouds – you will see no image. If the camera isn’t turned on and broadcasting – you will only see the “frame” where the image is meant to be. Because the data load is so huge from the incoming images, it limits itself to refreshing about every 30 to 60 seconds. This means the image will appear static, then reset itself. If you watch for a period of perhaps 10 minutes or so, you will notice appreciable movement against the background stars. The tracking is set on the nucleus of the comet, so the comet won’t appear to move – the background stars will each time it refreshes. There can also be unforeseen glitches, (such as viewer overload) so please be patient! Last… There will be no image until the broadcast time.
The live broadcast of Comet Garradd will take place on Monday, August 22 – 2100-0300 local Israel time (UTC+3). To give you some help figuring times, here’s a very brief listing that’s in absolutely no particular order:
Feel free to “take” any images you want and stitch together a video – or post ‘em to your favorites sites. If you enjoyed the broadcast, won’t you take a few minutes and thank the hardworking, generous crew at Bareket Observatory? I am very sure they would appreciate it!
