The first shot was earlier when there was still a lot of blue in the sky. The second one was probably 10-12 min. later.
Here's the set-up for these shots:
Canon 1D MKII (1.3 crop factor)
500 mm telephoto - 1.3X500=650mm
Tripod
miror lock-up function on
noise reduction on
10 sec. shutter delay
ISO 100
f 4 aperture
1/125 sec. exposure
auto white balance
It was cool. I set up on top of the parking deck over at my office. The moon was E SE and the sunset was due West. All I had to do was rotate the camera/lens on the tripod and take turns shooting both scenes. Here's a sunset shot.
