70 frames aligned and summed together (enhanced 1)This is the result of aligning 70 frames captured at ISO200, 8sec, f/2.8. with my Panasonic FZ20. Levels and gamma adjusted to view more stars.
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.
Don't forget to view the first image of the 70 frame sequence, and compare the difference.

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.

70 frames aligned and summed together (first image in sequence, with gamma=2)The first image in the sequence of images aligned and summed. It's a very noisy image, and most stars can't be seen due to the large ammount of noise. This image has it's gamma increased to make the noise visible.

70 frames aligned and summed together (first image in sequence)The first image in the sequence of images aligned and summed. It's a very noisy image, and most stars can't be seen even if one plays with levels, due to the large ammount of noise. I put this image with a higher gamma in the album as well, where it's more clear how noisy the original image really is.
