Details:
This 24 minute integrated image fixes Comet Lemmon against stars that were drifting slightly. Much more tail structure is seen in this image compared to a 2m45s integrated stack.
This short integrated time of less than 3 minutes is perfect to see the comet against fixed stars without incurring comet drift.
Tech spes: Fujifilm X-T5, Nikkor 180mm f/2.8 @ f4, iso 1600, Astrotrac tracking. This 7.5x5.0 degree f.o.v. shows the first 5 degrees of Comet Lemmon's tail. The moon was 52 percent illuminated under cloudless and windless conditions. Temperature was 31F, our first freeze this autumn.
