I don't know if something like this exists, so I have no idea what to call it. I would like some sort of timer mechanism that closes the shutter after a 5 or 6 hour exposure (shutter set to "T"). Basically, I want to shoot where I can set up the camera in the evening but will have to leave it overnight and recover it early in the morning. I want to capture the scene and the night sky, so the shutter has to close before I can get to it. I would appreciate any ideas.
Thanks,
Chris
