Comet 12P/Pons-Brooks appears beneath the imposing figure of the Andromeda Galaxy (M31) in this composite shot taken March 8. A meteor streak is visible at upper left. The photographer used an astromodified mirrorless camera and a 135mm lens at f/3.5 and ISO 600 to capture 20 minutes of sky data in 30– and 60-second exposures. The foreground is a two-second exposure at ISO 400.
