NGC 6188 is sometimes called The Fighting Dragons of Ara. As a fan of Game of Thrones or Hobit, I simply had to capture this beauty. Two dragons are clearly visible in the middle. Their heads are illuminated by the open cluster NGC 6193. I knew that this nebula is dim, so I dedicated a lot of time to it. Specifically, I stacked 86 narrow band pictures, each 5 minutes long.
Update 9.2.2023. I am happy to announce that this photo won Czech astrophotography of the month. I submitted several pictures already and finally, I managed. I am very happy.
