This picture made it to NASA Astronomy Picture of the Day (APOD) for August 5 ,2011 post#17 in this thread
I meant to capture about 45-55 minutes of 20 second exposures 10:40pm - 11:30pm, but fell asleep, woke up 3am.....and went outside to retrive the set-up.
The T1i battery had died, even though hot night the dew point was enough below the actual temp the lens stayed clear.
Canon T1i + Canon Lens 15-85 @ 15mm, each 20 sec exposure, over 370 images, just over 2 hrs of images.
Captured as RAW, import into Aperture 3, no PP whatsoever, just export as TIFF for StarStax to make startrails. All done in Mac OsX.
The moon rose around 12:30am, and its reflection is seen in the 2 garage windows as it ascended.

(btw I've never put a gaudy watermark across any of my images before, but once this went to APOD it's all over the web...)

StarStaX is a fast multi-platform image stacking and blending software, which is developed primarily for Star Trail Photography.
Besides star trails, it can be of great use in other settings, see here.
StarStaX allows to merge a series of photos into a single image, where the relative motion of the stars creates structures looking like star trails.
StarStaX is available as Freeware for Mac OS X, Windows and Linux.
