2015 Perseid Meteor Shower & Constellations
This is a stack of Perseid meteors from a timelapse I shot on August 13, 2015. I chose my 50 favorite meteors from 12:52 AM to 04:08 AM, rotated and aligned the frames so the stars are all in a fixed position, and masked in the meteors so you could see them radiating from Perseus. I added constellation lines for Cassiopeia and Perseus in this version.
The green color in the sky is caused by air glow. The Andromeda galaxy can be seen to the right of our Milky Way as Pleiades and Capella rise from the tree tops, facing roughly 58° north east on the compass dial. The Double Cluster is just to the left of a bright meteor near the middle of the photo. Polaris or the North Star is opposite Andromeda on the other side of our Milky Way.
Taken with a Nikon D810, Nikon 14-24mm f/2.8, DewNot heat strip, DewBuster Controller, Really Right Stuff TVC-34L tripod & BH-55 ballhead, and qDslrDashboard running on a Nexus 7 (2013 model) for shutter, ISO, and aperture ramping. These shots were taken at 14mm, f/2.8, 20 seconds, and ISO 5000 to ISO 800 during astronomic dawn. Edited with Lightroom / LRTimelapse, aligned with RegiStar, and stacked with Photoshop as 16-bit TIFFs.
