This week's astrophoto comes from Iair Arcavi of the Weizmann Institute of Science in Israel. Iair happened to be observing with the 200-inch Hale Telescope the night of the peak of the Perseid meteor shower. He managed to pull enough time away from his observations of Type Ia supernovae (discovered by the Palomar Transient Factory survey) to take some camera on tripod images of the shower.
I think that you'll agree that he did a super job in capturing the shower. You can easily see that the meteor trails all point back to the radiant (where the meteors seem to stream from) to the left of the open dome.
I had several request from both professional and amateur photographers who wanted to visit the site to capture the shower. Unfortunately I was unable to make it work for them as it isn't easy to gain access to the observatory grounds after hours. Of course it is much easier if you are scheduled to be using the big telescope.
