70 frames aligned and summed together

This is the result of aligning 70 frames captured at ISO200, 8sec, f/2.8. with my Panasonic FZ20.

Used a simple tripod and a remote shutter. Alignment was done by own software partly written in C, and partly in matlab (i'm using octave). sourcecode will be released when I'm done with my thesis.

It looks way better after adjusting levels apropriately as in some of my other photos. Don't forget to view the first image of the 70 frame sequence, and compare the difference.
