Comet Leonard's show and other comet photos

With just a few hours to go before the end of 2021, while the comet C/2021 A1 (Leonard) show is still going on, one last post of the year to thank all the readers of this blog. See you again in 2022, with the hope that there will be clear skies for everyone. According to M. Meyer, 2021 had 68 new comets (2020: 76, 2019: 64) of which 4 were amateur discoveries (2020: 5, 2019: 2). Top 3: PANSTARRS: 23; Mt. Lemmon/Catalina: 13/4; ATLAS: 8. Here's a short roundup of cometary photos starting with the most beautiful comet of 2021 and probably one of the best in recent years. (Click on each image below for a bigger version).
