This is similar to an image taken last year in the same location and about the same date. As with that image, this is also a composite of two images. The first was taken of Cathedral Rock as the moon was setting in the west. An exposure of 120 seconds at ISO 400 and an aperture of f/4 was used. The second image was taken a short time later after the moon had set allowing the fainter stars in the night sky to appear. This image was 5 minutes at ISO 400 and an aperture of f/4. To prevent streaking of the stars an iOptron Sky Tracker was used. The two images were then blended together.
