It is well know that you always anchor a night sky shot with ground features and the automobile turning your way add a lot of interest to the shot. Even with the earth rotation the 7 prominent stars of ursa major stand out. Paul
This is two shots stacked in CS6. One was 926 seconds, the other was 563. I was trying for a 30 minute shot, just to try it out. I aborted when this car turn toward the camera. I stopped again when a truck came from the other direction.
It was tough to be mad at them, they where checking to make sure I was ok and not stranded. It really wasn't a good night to try this. The moon was half full, and way high in the sky. It was throwing a lot of light, and blocking a lot of the trails.
For stacking I just put one on top of the other using layers, then changing the blending mode to lighten. That lets to bright stuff to show and the darks don't. I did have to do some masking. When the truck rolled up, all of the foreground was brightly lit.
I enjoy night sky photography, in fact I was going to go and camp in the flint hills over the long weekend and shoot night photography. The weather was going to be perfect and that area is classified as a dark sky. But as luck would have it we will have a near full moon which will spoil any chance of great sky's. I might try again in a couple of weeks. How did you assemble and stack your exposures? Paul
