Star trails over the city
Hi all,
I decided to have a go at star trails over the Brisbane CBD this morning. I've been wondering for a while if it is possible to capture a reasonable number of stars without having the city lights too overexposed... and the answer is yes! (although I had to selectively reduce the exposure of the city lights using a neutral density gradient filter in Lightroom 3). This is 75 minutes worth of 15 second exposures with the 15-85mm lens @ 24mm, f/7.1 and 400 iso, beginning at 4:15am. It was cold and windy up on the Mount Coot-tha, but worth the effort I think.
The two brightest streaks on the left are of course Venus and Jupiter, Orion is rising just to the right of centre, and Sirius is entering from the right hand side.
Thanks for looking!
Cheers,
Stephen
