Location of Photo:

Tucson, Arizona

Date/Time of photo:

2025 April 3 to April 11

Equipment:

50mm f/5 Refractor and IMX462 camera

Description:

Sequence of short color images showing Comet C/2025 F2 (SWAN)s coma and tail as the comet brightened from April 3 to April 6, then faded from April 6 to April 9-10 and then brightened a little on April 11. The Moon started to interfere with the images on April 11. The total time of the stacked images is short due to the comet's movement of about 4 arc minutes across the sky per hour, did not want to show a streaked comet or streaked stars in these images.
