IC4603 is a reflection nebula with a bright star in the middle named: SAO 184376. The nebula is located in the constellation Ophiuchus.
I took the photo in June 2019 during my visit in the Kalahari desert in Namibia. The sky is extremely dark in the area of the world and are great for astrophotography.
