| 説明 | A stacked sequence of 5 photos taken over a four minute period on Pi day (March 14, 2013). Fortunately other observers happened to stakeout the same spot and a young woman spotted the comet with a borrowed pair of binoculars after waiting in the cold for over a half-hour. I just aimed and hoped for the best. Taken with my very new-to-me Nikon D600 and not so new 300/2.8. Although I was chimping these shots, I hadn't noticed the star trails until I got home. Otherwise I would've switched to ISO 1600 and shortened the exposure time accordingly. The noise performance is definitely an improvement over the D700.Pan-STARRS = Panoramic Survey Telescope and Rapid Response System |
