Hi everybody! I'm going to take some night pictures with star trails, and which script do I need to use? And the parameter for that script, too!

Here is an example that I took on the Internet:

If you search the forum for "star trails" you should get some results.

To get long star trails like in your example, you will need to use an intervalometer script and stack the images using software on your PC. CHDK can do a maximum of about 35 minutes in a single exposure, but this only works on some cameras and the results are likely to be very ugly.
