hi everyone on AP,

i have recently been doing a few time lapse of the stars but there seems to be a problem with my interval shooting function..
i have a Nikon D5100 as the above says and i set it to do 100 shots at 30sec exposures with 45sec interval time.
even though i set it to do 100 shots it will always stop at 55.

does any one have the same problem or know whats happening? i have done some research but couldn't find anything on this problem

any help is much appreciated.

thanks.
