As captured by NASA astronaut Don Petit in the ISS, edited par moi. Don was the first astronaut to enter the SpaceX Dragon capsule in space.
Lest any photographer wonder why they might want to be in orbit. Seeing the stellar waterfall into the grooves of city lights… punctuated by flashes of lightning in the ember world below.
Don writes: “My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.”
