Why does my Nikon stop after 100 continuous 30-second exposures?

On Nikon DSLRs like the D7000/D3000/D200, I’m trying to shoot long star-trail sequences of about 180 frames at 30 seconds each. If I use Continuous mode with a locked remote shutter, or set the Interval Timer, the camera stops after about 100 shots / roughly an hour. Is there a camera limit causing this, and is there a reliable way to shoot more than 100 consecutive 30-second exposures?

I've encountered the same issue with my D7000.

To get more than 100 I have to intervene just before it hits the 100 mark. When doing star trails I set the mode to Continuous Low and lock the shutter button down with the corded remote.

Just before 50 minutes are up I come back to the camera and release the shutter button. When the 30 second exposure is over I lock the shutter button down again and it is good for another 100 shots. I've done up to 600 shots this way.

Yes. In Continuous release, you’re likely hitting Nikon’s maximum continuous-release limit of 100 frames. That’s why the camera stops after about 100 exposures when the shutter is held down with a remote.

For interval shooting, 30-second exposures usually need a little extra time beyond the nominal 30 seconds for shutter timing and possible processing. If long-exposure noise reduction is enabled, each shot can take much longer before the next one can start. So a 30-second interval may be too short.

What to do:

  • For Continuous mode: release and re-engage the remote just before the 100-shot limit to continue the sequence.
  • For Interval Timer: set the interval slightly longer than the exposure time (for 30-second shots, try about 33 seconds).
  • Make sure long-exposure noise reduction is off if you want back-to-back frames.

That should let you capture more than 100 exposures reliably.
