if you have the serial connector for your camera you can use nikons program to hold the shutter open for you at long intervals... also have you been pre cooling your camera before taking shots? in all my astro photography exsperiance i have leaned to leave my camera outside a good hour before i think about shooting anything...

some hardcore astro photographers actually attach peltier coolers to the back of their ccds (cmos) to bring the temps down.
