Comet C/2021 A1 Leonard: a image – 07 Dec. 2021.
Despite the poor weather conditions of this season, making hard for us to track it daily, we succeeded capturing this new image of comet C/2021 A1 Leonard.
The image above comes from the average of 14, 120-second exposures, unfiltered, remotely collected with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at the Virtual Telescope Project. The robotic telescope tracked the apparent motion of comet C/2021 A1 Leonard, so stars left short trails on the background. Images were combined using a sigma-clipping technique, to reject stars interference as much as possible. The sky was not perfect, but considering this very cloudy Fall 2021 in Italy, we were lucky!
