This is my first attempt at capturing star trails looking out over Lake Burley Griffin, ACT. The light trail to the right is a flight path, I left it there as I thought it added interest.
110 × 30 second exposures @ f5.6 ISO100 (total elapsed time just under 1 hour)
1 × 8 minute exposure @ f5.6 ISO100 (to pick up the foreground detail)
Stacked all 110 images in photoshop and layered the 8 min exposure over the top.
