![]() Basically where you are on earth starts to rotate around to the front of the Earth’s path through space at midnight, so the sky above you collides with more comet dust from then until astronomical twilight starts before dawn, as this article explains:Īsk the Naturalist: What’s the Best Time and Place to See Meteors? Update March 2016: One more thing, meteors are more common after midnight, so I usually arrive on site around 11 pm to give myself an hour to set up before I have to start shooting. You’ll need a tripod of course, and your sequence of still images will turn out best if you use a remote switch that has an intervalometer (timer) function. If you’d like to explore time-lapse photography yourself, download the free VirtualDub software which can convert a sequence of JPEG files into video. Adjust your exposures per minute and video frames per second math to figure out how fast you want your shooting sequence to play back. So if I’m using a slow frame rate of 12 frames per second to make the meteors more persistent in the video, I’ll end up with almost one second of video per minute of shooting. I set an external timer (intervalometer) to take the next shot one second later, so I took one very 6 seconds, or 10 shots per minute. With the nearly full moon last night, there was enough light that I was able to reduce my exposure time to 5 seconds. ![]() On a dark night your exposures may be 30 seconds or more, so at 24 frames per second each hour of shooting will give you less than 5 seconds of video. Fortunately our eyes and minds are quick enough for us to perceive the meteors with some persistence even though they show up for only 1/12th of a second. ![]() To make the meteors last more than 1/30th of a second, you may want them to be present for two frames of video, and assemble your video at a relatively slow frame rate of only 12 shots per second, so in video formats that play at 24 to 30 frames per second, the meteors show up for at least two frames. Each frame is a 5 to 30 second shot, but video is 24 or 30 frames per second. When deciding how long to shoot, bear in mind that this is a time-lapse video, so in playback as video everything is dramatically sped up. Lets do a little math to figure out how your still shots will transfer to video. If you shoot continuously for a while and catch a couple of hundred exposures or more, you can even assemble those shots into a time-lapse video. When shooting night landscapes and trying to catch meteor showers, I like taking long exposures one after another, so you catch anything which flies through your camera’s field of view. The Perseid Meteor Shower runs from July 17 – August 24, with peak night occurring around August 12-14.
