There are two nice telescopic comets at present, 2023 E1 (Atlas) in the northern hemisphere and 2021 T4 (Lemmon) in the southern hemisphere. This image is a montage of both, captured with identical eleven inch RASAs and 30 min integration time. Comet 2023 E1 is about mag 9 and 2021 T4 is about mag 10.5. The telescope tracked the comet so long integration tails the background stars.
