This image is an HDR stack of 47 different bracketed exposures during totality, with shutter speeds ranging from 1/8000 to 2s. All of the images were taken during the first 2 minutes of totality, before max eclipse. The star system Zeta Piscium is easily visible to the left of the eclipse. Several high pass filters were used to extract the coronal structure while not adding excessive detail. Adobe Camera Raw was also used to adjust the color of the sky to a deep blue color, which more closely resembles what I saw with my own eyes. Other common adjustments were made to touch up the final image, such as exposure, contrast, shadows, noise reduction, etc.
