This is a stack of 195 frames from a timelapse. I started out with a median stack mode of all 195 frames in Photoshop to remove people, car headlights, lightning bugs, etc. for a base layer with no noise. This also created a very clean sky with nothing but Polaris or the North Star. Next I masked in 6 frames of lightning in the distance from a thunderstorm passing through. On top of that I masked in a layer of star trails and moving clouds in lighten mode, stacked with Advanced Stacker Plus. Finally, I masked back in three frames of people and tripods.
Camera settings: 14mm, f/2.8, ISO 2500, 15 seconds.
Equipment used: Nikon D810, Nikon 14-24mm f/2.8, MeFOTO RoadTrip tripod. Edited with Lightroom and LRTimelapse. Stacked with Photoshop and Advanced Stacker Plus.
