Comet Nishimura (C/2023 P1), at left, captured at dawn on September 7, 2023 with the sky beginning to brighten with morning twilight colours. Plus the last quarter Moon was lighting the sky and landscape with moonlight. The comet appears with Venus, at right, beginning its morning sky appearance for 2023/24. In addition, the star cluster Messier 44, the Beehive, is at top right. The smaller Messier 67 star cluster is just above Venus. The comet was set amid the stars of the Sickle asterism of Leo the Lion, just rising in the east. The comet sports a faint blue ion tail, with the comet seemingly pointed toward the sunrise point; it was moving down and closer to the Sun at this time. The stars Mu and Epsilon Leonis are above the comet (upper left and upper right) at 4th and 3rd magnitude respectively. So the comet head was about 3rd magnitude or brighter. The ion tail was about 3° long here but fades into the twilight and moonlit sky. This is a stack of 6 x 30-second exposures, all tracked, with the Canon RF28-70mm lens at 70mm and f/2.5 and Canon R5 at ISO 400, blended with a single but still tracked image for the ground to minimize their blurring. All on the Star Adventurer Mini tracker. Taken from home on a dewy but very clear morning.
