Airglow over Cadillac Mountain - Full Sky

On July 26, 2014, Matt Pollock and I captured a spherical panorama of green airglow and the Milky Way over Bar Harbor from Cadillac Mountain in Acadia National Park, Maine. This crop is an ~6mm view of the whole sky. The full sphere consists of 5 photos of the sky blended with 4 photos of the ground. It took about 22 minutes to shoot from 11:30 – 11:52 PM. We spent the rest of the night shooting a timelapse for star trails.

Camera settings: ISO 6400, f/2.8, 40 seconds, & 3550°K white balance for the sky blended with ISO 6400, f/2.8, 160 seconds, & 3786°K white balance for the ground.

Hardware used: Nikon D810, Nikon 10.5mm f/2.8 (lens hood shaved off for full frame use), Promote Control, and Really Right Stuff TVC-34L tripod with leveling base & multi-row pano package.

Software used: Edited with Lightroom, stitched with PTGui Pro, and blended with Photoshop. Pixel Fixer was used with a dark frame to remove hot pixels from long exposures at high ISO.
