Comet C/2021 A1 (Leonard)

Posted: 20 December 2021

7x50 binoculars


1808 MST: Spotted Comet C/2021 A1 (Leonard), 7x50 binoculars. It was very faint in the twilight sky.

I began taking photos using the D850 DSLR and 70-300mm lens on a camera tripod. As it has been throughout its evening appearance, the comet continued to be faint and low in the western sky. Here are two photos that show the comet. A faint tail is visible.

f/5.6, 1 second, ISO 800, FL 300mm

This photograph shows the comet over Kitt Peak National Observatory (65 miles away). (An example of poor outdoor lighting is evident on the house in the foreground.) Click or tap on the photo for a larger version.

Once the just past Full Moon rose over the hill to the northeast, I ended comet photography.
