Airglow and Star Trails over Cadillac Mountain – Little Planet
On July 26, 2014, Matt Pollock and I captured a spherical panorama of green airglow, the Milky Way, and star trails over Bar Harbor from Cadillac Mountain in Acadia National Park, Maine. This is a “little planet” projection of the panorama. I like how the star trails almost look like Earth’s magnetic field!
The full sphere consists of 5 photos of the sky blended with 4 photos of the ground, plus another 249 images for the star trails (3 x 83) layered on top and can be explored on Roundme: http://round.me/tour/4844/view
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. Star trails were shot at ISO 1600, f/2.8, 25 seconds, & 3550°K white balance. I removed several airplane trails before stacking.
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. Dew-Not heater strip powered by a DewBuster controller and Goal Zero Sherpa 100.
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. Star trails were stacked with Advanced Stacker Plus.
