Hi guys,
I have just started photography and have a Nikon D5000 and am trying to photograph star trails. I have the stacking software so am taking the "multiple, short(ish) exposure time" technique, and stack them, over the one long shot.
I took some on Sunday night and when I stacked them, there were gaps in the star trails. I am taking them at 30sec intervals, (on the "S" setting) not sure what the aperture was im afraid, with a cable remote. I noticed that on the test shot (to make sure scaffolding I was getting in shot was in focus) that after the 30 seconds of shooting, there was another pause, possibly a further 30 seconds before the photo showed in the live display. I presume this is the reason for the gaps in the stars, but im wondering if there is anything I can do to stop these gaps? I was thinking of going down to 10 second exposure, so more photos to stack but no issues with the software doing the work.
Any ideas greatly appreciated.
Thanks
Matt
