circular star trails | August 17, 2005

circular star trails || canon 350d/ef17-40L@17 | 15 min | f4.5 | iso200 | tripod
a combination of two photos of 10 minutes and 5 minutes exposures in order to get longer trails. photos shot at longer than 5 minutes exposures are very noisy so combining a few shorter exposures will produce cleaner results. it took a few tries to find the northern star to compose the frame. unfortunately a few clouds smeared the shot.

shot at a lake in québec.

PS. we're in oxford, england at last. it's a beautiful place and we'll be visiting London in a few days. thanks to all of you who were concerned about the trip delays.
