In my mind, there is only one thing to do when a cresent moon and a great sunset coincide. Take pictures of course. Where to place the moon in the frame becomes the big question. I liked how the brighter red clouds running through the bottom of the frame balanced the more-left positioned moon.
This picture shows how big you should expect the moon to be in your 250mm APS-C sensor format images. Full frame DSLR owners would need a 400mm focal length for the moon to be reproduced at this size.
