Stacked 550+ images to make this star trail. Captured 2 Leonid meteors which are in the picture, though not so easy to find. Using a 30 sec exposure, f/3.2 and ISO 400 to allow the color of the stars to not be overexposed. Then all images are stacked in Photoshop and adjustements made to bring out the different colors.

While trying to capture Leonid meteors I set the camera up on continuous exposure and just shot for about 4 1/2 hours, over 550 images in all. I got two nice meteors and made this star trail by stacking all 550+ photos. By using a low ISO of 400 the stars are not overexposed and you get a lot of color variation. Shooting north I had the moon behind me illuminating the foreground so I didn't have to blend foreground and sky in post.
