Cepheus the King
An ancient Greek tale of pride and passion is played out across the sky, involving five constellations including Cepheus the king. In Cepheus there are stars being born and stars at the end of their lives, including those which will die in a blaze of glory.
Twice a year the Sun sets between the skyscrapers of the east-west streets of Manhattan. This dramatic effect was dubbed"Manhattanhenge" by astrophysicist Neil de Grasse Tyson. The tall buildings are reminiscent of the stone uprights of Stonehenge. If the Manhattan street grid were precisely aligned with the compass points, this effect would occur on the spring and autumn solstices, but it actually happens in January and July, since they're thirty degrees off.

T-RECS has some splendid shots of clear night skies in Yosemite and Death Valley in this video which you can see at http://vimeo.com/43797471. Some of the objects are also, very helpfully, labelled. The opening images show the Summer Triangle, an asterism composed of Vega, Deneb and Altair. I can often see the Summer Triangle, but it doesn't have the background of all those other stars shown in the video.
