Last weekend I was experimenting with capturing star trails. I tried taking a set of 9 photos of the stars and Milkway (ISO 1600, f/2.8, 30 seconds exposure). Here is resulting combined photo (stacked with StarStax):
The resulting image is very blurry. Can anyone tell me what to do differently next time so I get a better shot? My theories are:
- I should have avoided the Milkyway, as it is not going to come out crisp in a long exposure shot lasting this long.
- Wind may also have been a factor. I have a very cheap tripod, and it was rather windy that night.
Anything else that may attribute to this type of blur?
As requested, here is a single photo from the set:
Notice that I composed the shot with the Milkyway in it, which I believe is adding to the blurring effect in the final stacked imaged.
Also as requested, here is a 100% crop of the above image:
