Hi, recently I've been taking this camera out for night shots at places with very little light. I don't like the results- a lot of red and blue pixels showing, and there are almost no details in the pictures- clumsy, clumpy, 'grainy' noise. After a few shots the pictures gets even worse as the sensor heats up (patch of red noise builds up from the bottom left corner of the frame). I had to shoot them at iso200 max (but almost all were at 100)- no choice as the back has such a poor 'high iso' capability.
Shown here is a 100% crop of centre of the 8th shot from that night out.

Is there a technique for long exposures on Hassleblood digital backs that I do not know of?
Another question: Are the current generation Hasseys better at this?
Should I just forget about it and just shoot on film or on 35mm digital?
Thanks.
