I'd like to share some of my recent star shots taken with the new 5D Mark III. I am approaching this astro-landscape interest completely by trial and error, which is made possible by the instant feedback of the DSLR. During this learning process, I have found that (unlike the T3i) no long-exposure noise reduction is needed with the 5D3. As for high ISO NR, I'm not sure yet. Thus far, I am not using it. I welcome all tips and critiques on my images!
The first one was taken just east of Phoenix looking south over Picketpost Mountain during the Oct new moon. ISO3200, 32sec, 14mm Rokinon at probably f/5 or 7.
Second shot was taken on the same night from the same spot, but looking north. ISO500, 31min, 14mm at probably f/11 or tighter.
Third snap was taken on the eastern flanks of the San Francisco mountains near Flagstaff AZ on a crystal clear new-moon night in Sept. ISO1600, 30sec, 14mm, f/2.8.
Finally, I grabbed this next image on the same night shooting just above the southern horizon. The "star trails" had me really perplexed once I got home and uploaded all the photos to the Mac. Since I had been pointing the camera to the south, the trails just didn't make sense. I did finally figure it out.... Anyone want to take a stab? What I absolutely love about this new photography habit of mine (especially night photography using manual everything) is that it really makes you think!
