This is a composite image of the Comet NEOWISE and the water tower at the Linn County Engineer facility at Highway 13 and County Home Road, about 2.5 miles north of Marion, Iowa. Both the comet and water tower were photographed from this same location, but at slightly different times and positions in the sky on Wednesday, July 22, 2020. The water tower was captured at 9:41 pm CDT, and is a 13 second exposure at f/4.5, ISO 160 and 34mm focal length. The comet was captured at 10:22 pm and is a 15 second exposure at f/4.5, ISO 2000 and 26mm focal length. The background is a stack of four images to reduce noise. The water tower was once part of the Linn County Home, which was operated from 1892-1977. Nikon D7200 DSLR camera.
