C/2021-s3-panstarrs
About this celestial object
Early evening sequence of C/2021 S3 (PANSTARRS) in delicate twilight.
The comet shows a diffuse coma and, depending on activity, a fine tail—a classic appearance of a wandering comet.
77 short exposures (a little over 13 minutes) at 21.6° altitude and 74% humidity, taken at 250 mm f/5, secure a steady core against the starry carpet.
The short total time keeps native motion small and preserves natural star images.
