Two globular clusters very close to each other seen through the dense star field in the direction towards the centre of our Galaxy, in the constellation Sagittarius. These systems are relatively young for globular clusters, being only about 10 million years old.

They can be spotted between gamma1 and W Sagitarii (see finder chart below). NGC6522 (right) sits right in the centre of Baade’s Window
