A stunning composite of 325 photos takenevery 30 seconds over 162 minutes shortly after sunset in southwest Iran earlier this month. In the desolate snowy scene, illuminated by moonlight, the bright streak behind the lone tree is the planet Venus setting. To wit:
What divides the north from the south? It all has to do with the spin of the Earth. On Earth’s surface, the equator is the dividing line, but on Earth’s sky, the dividing line is the Celestial Equator — the equator’s projection onto the sky. You likely can’t see the Earth’s equator around you, but anyone with a clear night sky can find the Celestial Equator by watching stars move. Just locate the dividing line between stars that arc north and stars that arc south. Were you on Earth’s equator, the Celestial Equator would go straight up and down. In general, the angle between the Celestial Equator and the vertical is your latitude.
The ISHU – a €340 scarf designed by Access All Brands with ‘anti-flash’ technology engineered to blow out the exposure of flash photography, supposedly thwarting pesky paps (and, presumably, opportunistic mates at the ugly end of a long night out).
A long (37 minute) exposure of the moon passing across the sky by Finnish photographer Janne. Petapixel’s Michael Zhang explains:
Janne was shooting with a Nikon D800 and 100-300mm lens at 300mm, f/8, and ISO 100. The trick behind the shot was a 10-stop neutral density filter, which greatly cut down the amount of light hitting the sensor and allowed Janne to shoot a 2258-second exposure.
1. Use a tripod, or stabilize your camera on a flat surface. 2. Set your ISO setting as low as it will go. 3. Set your aperture to F10/F11. 4. Set your exposure time to 2 or more seconds. Then, when you snap the long-exposure photograph, zoom your lens all the way in our out to stretch out the lights you see.

some guy was standing in the bus lane, relieving himself in a road
drain. I instantly thought of Broadsheet.” (Iain B)
