This was located about 2/3 up the imaginary line going from η Herculis to  ι Herculis. After seeing M76/Dumbbell Nebula, this was quite spectacular!  Numerous bright stars could be seen in the dense centre but because it wasn't perfectly clear, I could not make out individual stars. There were bight stars in the periphery.
