Astrophotographer’s statement “I threw Sirius out of focus and took this series of short exposures (1/25-second) with a 150mm telephoto lens on a Canon 5D Mark IV earlier this month [January, 2021]. The images are raw right out of the camera and not altered in any way. They show not only the star’s remarkable color changes but also its changing brightness as eddies of air of different temperature and pressure pass by.
