Am currently welding up and helping restore an old Subaru Impreza and have spent several of the last weeks nights out with the camera.
Have made some time-lapse movies of the nearby estuary and other star related photography. Last night we went out to try to capture some meteorites. Finished about 3am then drove home and started processing them.
Have discovered the D3 isn't keen on long exposures in time-lapse constant operation. It suffers badly from banding across the frame, Starts with almost indistinguishable narrow bands but gradually become wider and more pronounced. Not too bad for a movie but would be no good for stills.
I was making an exposure of 32 seconds at ISO800, every 34 seconds for about two hours, the banding became apparent after about 15minutes. I have tried 32 second exposures every minute with no evident banding after two hours, so it would seem it's the lack of recovery time which is the issue. it was pretty cool late at nigh with a cold strong wind, so it wasn't ambient temperature.
Will post some more pic shortly.
