NGC6309 – Exclamation Mark Nebula
Object Type: Planetary Nebula
Location: Tarragona – Spain
NGC6309 is one of the two planetary nebula with the nickname “The Box”, (the other is NGC6445 in Sagittarius), but after my experience with it, I prefer name NGC6309 like Stephen J. O’Meara in his book “The secret Deep”: The Exclamation Mark.
