Nikon D750 Equipment Beginner Troubleshooting

I'm new, and after my second night I'm seeing some weirdness when the camera doesn't take as many pictures as I told it.

I'm just trying to get Orion as a first target.  

Using the built-in timelapse feature, I have the D750 set to take 256 images, one second apart.  My images are 3s long, ISO 800 with a 105mm F2.8 MicroNikkor lens.  Just sitting on a big tripod.

But it seems like it doesn't take the full 256 images.   There were like 180 or so.   Also when taking the darks, I told it 64 and it quit after like 20.
It didn't give me any battery warnigns or anything.   Cold out, like 5 F last night.

What is going on?      I have many questions, I am just trying to start somewhere - and if I can't trust my camera to do what I say…

Not sure I understand what you're trying to do. Are trying to create a time-lapse video or use the intervalometer?

Is it possible that you put intervaltime on 1 sec. If so you should put intervaltime on 4 sec.
3 sec exposure and 1 sec of pause between 2 frames. 
Also be sure that date and time are correct in your camera.

Hi Eddy,
  I was worried that it was something like that - that the 'timelapse' feature I am using as my intervalvometer would not work correctly if my exposure time was longer than the interval time.      I'll experiment with that change before I go out again.   Date and Time are correct.    

  I am also worried that maybe the camera builds up a backlog of images to write to the SD card and eventually cannot keep up and quits, or something like that.

Just trying to use the built-in feature as my intervalvometer.   It is nice that I don't need a shutter release cable or any extra wires.

If the backlog is the problem you just take 2 or 3 seconds as pause. Meaning  interval is 5 or 6 sec. 3 sec exposure and 2 or 3 sec pause. You have to find it out with your sd-card.

If you want to take 3x3second shots 1 second apart then you must set the interval to 4 seconds and tell it to do 1 shot and 3 intervals. You must also set a total shooting time of at least 12 seconds. It's all here:
https://imaging.nikon.com/support/digitutor/d750/functions/timelapsephoto.html

The intervalometer on my D7500 has a similar logic, the interval must be long enough for all shots in the shots per interval. E.g. if you ask it to take 15x10second shots at 5 second intervals, it will take only the first picture because 15>5 so the remaining shots per interval are cancelled. Took me 3 years to actually read the manual and figure out why the intervalometer wasn't working like I thought it should

Cheers,
