Because of bad weather conditions in central Europe and Germany there was not even a little cloud gap

for observing the comet C/2021 A1 (Leonhard) for 9 days in my region. But in the morning of the 10th of December the dense cloud layers situated in the southern German regions

openend 3 hours for a clear sky. So let's take the last and only chance.

*mag  = > light magnitude: Up to mag +3 or +4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag +6-7.

The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; + 3,5 M31 Andromeda, pale shiny oval)
