This composite image consists of 11 sky at ISO 6400, f2.8, 15mm, 15 seconds each. The ground was a single image at ISO 3200, f2.8, 15mm, 30 seconds. The sky was stacked in Starry Landscape Stacker and I composited in Photoshop. Adjustments to exposure, curves, and saturation were also made. Merging the composite is always a challenge getting the transition correct.
Cheers!
