NGC 6729 and NGC 6723 are both amazing targets in the southern sky, located in the Corona Australis and Sagittarius constellations respectively.
Corona Australis is often called the “Southern Crown,” and it’s home to a spectacular dark molecular cloud that’s pretty fantastic.
NGC 6729 is a reflection nebula, which means it doesn’t emit its own light but instead reflects the light of nearby stars. It’s actually part of a larger star-forming region, so what you’re looking at are the birthplaces of new stars! It’s a bit like a celestial maternity ward.
NGC 6723, on the other hand, is a globular cluster in Sagittarius, filled with hundreds of thousands of stars. The light from these densely packed stars has travelled around 28,000 light-years to reach us, give or take.
