Description

High resolution image of C/2021 A1 Taken at UTC 21:00, Nov.30.
It seems that there are at least two dots close to the the nucleus. I have taken two groups of exposure, and the dots exist in both groups. These dots moved with the almost same speed as the nucleus. It's unlikely to be noise.
The picture was taken in Beijing city, Bortle Scale 8.

Camera = ASI290MC
