Description An interesting area of the sky with lots of faint nebulosity.  RCW102 is near the centre with RCW104 to the upper left and RCW 103 (a supernova remnant) to the upper right.  The very bright small nebula almost exactly at the centre is the planetary nebula ESO 225-9 or RCW101 which is also known as the Ant nebula.
