I've shot a few star trails over the past few months, and a few times I've run into this problem of 'wobbly' star trails. I've tried weighing down the , but even on really still nights with no wind it ends up really scattered. All the photos were triggered by a remote (so I didn't touch the camera between photos).
I have a relatively cheap , but I don't have the funds (broke uni student) to get a proper heavy . Am I doing something wrong? Anything I can do better in terms of reducing and preventing the scattered stars?
600D, 18-270mm .
19 photos @ 400, f/3.5 and 30 seconds .
I was set up on my veranda, there was no wind at all.
450D, 18-55 kit + fish eye extension
100 photos @ 1600, f/3.5 and 30 seconds .
set up in a field, slight breeze. I had my car parked behind the to block the breeze a bit (and for me to sit and wait in )
