Photo astronomy: Practice with Gimp photo stacking capability Night 3.

My Fujifilm HS25EXR camera feels like a ton compared with my SAMSUNG WB150F compact camera, we resumed our photoastronomy experiments with the SAMSUNG camera.
We took three photos of the night sky, using a tripod and the same settings and same sky coverage. They were all taken approximately 10 seconds each,, ISO 1600. f/4.0. With these three photos stored in a SINGLE directory, we opened them under GIMP (open as layers). Select them all! and stacked them as one composite image. Here is the final result:

You have to click on the photo above to view the stars. Here is a magnified view of the central portion as produced by the display program in Linux.

We ask our readers to click on the photo and zoom them for higher magnification.We repeat our experiments tomorrow!
