Yes Arthur, it's normal. It is called 'Amp Glow'. It is caused by the sensor being electronically affected by a small Amplifier which is right next to the sensor. Unfortunately the Amp can't be moved to another position, so everyone has the same problem. You can see the amp glow here on some of my images. See the top left corner in each one: Cooling does help a bit, but the longer the integration the more the Amp Glow. There are some new sensors that have reduced the amount of Amp Glow, but not in the top end cameras, only in the cheaper versions so far.
