So the other evening, the last at Mont Cru, nature finally regaled me with a beautiful thunderstorm. So I set myself up and shot lots of 30 sec exposures during an hour of awesome display. Many pixs were useless, between nothing captured and a complete white out, but some dozen seemed very nice like this:

But when I examined the pics more closely, I discovered a lot, maybe a dozen, hot pixels. I thought that this would be rather unacceptable for a camera like that. But after some reading like this (http://www.mediachance.com/digicam/hotpixels.htm) maybe it was not that bad at all.
So I tried that hot pixel elimunator in that link, with this result:

The original crop on top shows three hot pixels, from left to right a blue, red, and white one. The white light on the left is a light indeed, no hot pixel. The bottom crop after applying the eliminator, only shows a little bit of the red one left
