Summer Stars….


Did you miss sleeping out under the stars during the Perseids this year? Photographer David Wilson once again captured the serenity and beauty of Northern California skies in summer.

Photographer David Wilson once again captured the serenity of the Northern California skies in summer and opened a window into beauty. All you have to do is open the window.

Do you remember the timelapse of the Perseid meteor shower being watched by the rabbit that Wilson filmed last year? It’s worth watching again.

Thank you, Kym 🙂

Upper timelapse, Aug 12-13, 2017:

Perseid meteors burst out of a starfield above a Southern Humboldt, California skyline during the Perseid meteor shower of August 2017. Most meteors are visible in the first half.

Watch Saturn, in the lower right of the Milky Way, briefly glow more brightly at about 3 seconds into the video after the title fades.
The Moon, 65% full, rose to the left, illuminating the sky and the hills in the distance.

Lower timelapse:

Published on Aug 14, 2016The Perseid Meteor Shower as seen looking north toward Polaris on the night of August 11 from 10:15 PM to 3:01 AM on August 12. A jackrabbit came to watch, too, and becomes silhouetted against the horizon on the right side about a third of the way through. If you view in HD you might discern a few small meteors that come by in the area above his head. This timelapse sequence comprises 565 individual high resolution still photographs shot with a digital SLR. Then, much as you would make a flip-book animation, they were assembled into a video that plays them back in order for us at 24 frames per second. It required 12 minutes of real time to make one second of the video, which is why the motion is so fast when played back at 24 stills per second.

Some of the lights you see whizzing by are airplanes. The meteors flash and disappear, while the planes move across the frame. Why? Because during each 25-second exposure, a meteor appears for maybe a second. It doesn’t appear in the next picture. But an airplane crosses slowly across the entire 25-second exposure, and it is in the next frame as well, and probably in the next and maybe the next. Thus an airplane zooms across the whole field, while the meteor is a single streak, usually not stretching anywhere near across the entire sky. There are a great many of both in this video, and probably the larger it can be viewed, and in HD, the more one will see.

What exactly is a timelapse, or time-lapse?

Did you ever make a flip book, where you drew a slightly different picture on each page, and then as you flipped through them rapidly you could see an animation? Well, that is much like a timelapse.

To make a Time-lapse, I set my camera to take a picture at regular intervals. I might let it do this for hours. At the end of a certain amount of time I will have a whole bunch of pictures, which are essentially just like the different pages in that flip book. When I play them back rapidly in the form of a movie, each slightly different image becomes one frame in the movie. Here they are played at 24 frames per second. It took about a minute to shoot two frames of the movie, and it takes 24 frames to make a second of movie.

In this year’s Perseid timelapse, it took 8.4 actual minutes to make a single second of movie, or 84 minutes to make 10 seconds of movie.
