I have a Nikon D5300 and experimented shooting star trails but encountered a problem that I believe may be related to the Interval Timer setup. In order to take 99 30-second exposures I set the starting time to Now, the interval to 32 seconds, and the number of intervals to 99.
On my first attempt the camera stopped taking photographs after 41 exposures. I tried a second time and it stopped after only 20 photographs.
I found the passage below in the Reference Manual and was wondering if the problem might be that I did not set the interval long enough to allow the camera to record some images to the memory card:
“Because shutter speed and the time needed to record the image to the memory card may vary from shot to shot, intervals may be skipped if the camera is still in the process of recording the previous interval.”
Any help or suggestions will be welcomed.
