Amateur astronomy enthusiasts may be content with shooting the stars with a DSLR through a telescope, but what would a consortium of astronomy institutes use for photographing the night sky? The answer is the OmegaCam, a giant 1,700-lb camera found at the heart of the largest telescope designed for visible light surveying: the VST. It uses 32 separate CCD sensors that work together to form a giant 268-megapixel sensor, capturing 30 terabytes worth of photographs every year. The photograph seen above is the first released photo shot with this massive camera.
Update: We’ve posted some photographs of OmegaCAM here.
Photographer Ben Canales created this great video tutorial teaching the basics of shooting the night sky. He goes over how to shoot quick test shots to set up your composition before discussing more in-depth tips and tricks for capturing the final shot, including the “Rule of 600″:
[...] the quickest way to determine the longest exposure that is possible for any given focal length lens, without the stars streaking, is to divide that focal length into 600. (This is the formula for 35mm. Larger formats are laxer, smaller formats more unforgiving). [#]
For example, with a 50mm lens on a full frame camera, you can only expose for 12 seconds (600/50=12) before the stars turn into star trails. It’s a good rule of thumb to keep in mind!
Time-lapse videos of the night sky usually feature breathtaking views of stars spinning in the background, but here’s a night sky time-lapse that offers a different perspective — instead of having the stars rotate overhead, the sky is fixed while the foreground spins around the frame. The original (and traditional) footage can be found here.
What you see above is the largest true-color photograph of the night sky ever created, shot by 28-year-old amateur astrophotographer Nick Risinger using six astronomical cameras. It’s not just the view of the sky from one location, but is instead a 360-panoramic view of the sky taken by trekking 60,000 miles across the western United States and South Africa starting in March 2010. The final image is composed of 37,000 separate photographs. Check out the massive zoomable high-definition version of the photo here.
Thanks for the tip Udi!
This is a stunning time-lapse video of an entire night at the ALMA Array Operations Site in Chile (the largest astronomical project in existence). The antennas point at the same part of the sky at any given moment, so their movements are perfectly synchronized. If you think watching a sunset is beautiful, wait till you see our galaxy come into view in this video.
P.S. This video could do with music. We recommend playing some Sigur Ros in the background while watching this.
Last night there was a total lunar eclipse that just so happened to coincide with the Winter solstice. If you missed the eclipse in person, University of Floria professor and photographer William Castleman created this beautiful time-lapse video with photographs he captured from Gainesville, Florida.

You don’t need fancy camera gear to capture beautiful images and video of the night sky. The above video shows a timelapse created using 1262 photos captured with a Canon 20D at 30 second exposures and ISO 800. At the end there’s a star trails photo created by combining all the stills into a single image. It’s a great 1.25 minute dose of relaxation and inspiration.
If you live in an urban area, you probably don’t see the night sky very clearly due to light pollution. Luckily, there’s videos like this one to remind us how beautiful the sky above is when there aren’t artificial lights drowning out the stars. This is a high-definition time-lapse of the Milky Way floating across the sky.
