Well this shot was a trial of long exposure. Can't figure out what the purple lights are on the top. There was no back light in that direction. Will have to play around a little to figure that one.
Update: Andy Pagett says:
Hmm I don't fully understand what you put there but let me see if I can explain!!:
What you did: You had noise reduction turned OFF... you held the shutter open for 30 minutes by whatever means (cable?). After 30 mins the shutter closed and you got that pic
What should have happened: You would have noise reduction turned ON, you would hold the shutter open for 30 mins as you did above. Once you let go and the shutter closes again, the camera would then lock up for 30 mins (if you look in the finder it says Job-NR in the bottom corner) whilst it does the dark frame subtraction. So the whole process takes twice as long, but gets you a clean image.
Thanks Andy for this comment.
