Re: dust or dead pixels?

The pixels will dissapear when you activate the lon exposure noice reduction. After every piocture taken with a long exposuretime will a second picture be taken. This picture is with the shutter closed and of the same exposuretime. this black frame will be substracted from the original picture and the noice will dissapear.

What you see is sensor noise. The temp. of the sensor will generate this noice, with longer exdposuretimes it become visible and is normal for every sensor (some will show more then others) When the sensor get warmer you will see more of this pixels.
