Description

After showing you recently the largest globular cluster in the northern hemisphere - M5

(3'' bigger than M13), now the, my personal opinion, most beautiful one - Messier 3, in Canes Venatici (of course, in the northern hemisphere).

Data combined from 2017 and 2019, as I used the short period until the Moon came up during the Easter weekend.
