Dear All,
Sorry if this topic has been discussed before but i can't seem to find it. I had the D800 since July. I love the camera until recently, i had an opportunity to shoot long exposure night shots. I noticed any shots longer than 1 minute i would get colour artefacts like confetti on the picture?
I had turned the LENR on and it still persist. What am i doing wrong? I have tried to contact the local nikon site but the technical support is down or something that page won't open.

please find the attached sample pictures of different exposure time.
please note samples have been cropped to see the artefacts better.
83sec exposure, 14mm, ISO100, f/8
