IC 4628, also called Prawn Nebula is an HII region in the constellation Scorpius. Due to very low southern declination, it is poorly visible even from southern Europe. The southern hemisphere is obviously a better place to observe/photograph this deep-space object for example in Namibia, where this beautiful nebula rises very high in the sky. The open cluster on the left side is called the Northern Juwel box cluster.
