An impressive arc shaped rim of HII structure is located in the tail of the Scorpius constellation and known as the Prawn Nebula. The centre portion of the nebula is very bright and it seems there is a faint reflection component embedding it.  Bright stars are part of Open Cluster named Trumpler 24 which shines at magnitude 8.6 and spans over 60 arc minutes representing approximately 250 light years across. 
The image was taken with a 6 inches Orion UK Newtonian and a QSI 583 WS riding in a NEQ6 SW mount for a total exposure time of 3 ½ hours
