Fig.25 - Moonrise on October 13, 2019 above Chöpfenberg, Switzerland. Composite of an image during the blue hour (before moonrise) and several additional images after moonrise taken 3 minutes apart with a fixed camera (camera on tripod). Nikon D850, Nikon AF-S 70-200 mm f/2.8G VRII at 116 mm. The exposure time had to be adjusted every third or fifth image due to the brightening of the moon. The moon brightness was fine-tuned in Adobe Photoshop (using the NEF files). The expected position of the rising moon was determined with the excellent Swiss PeakFinder app.
