  What it is

It consists of ionized gas, dust, and reflection nebula. The name Elephant Trunk derives from the long dark dust lane. The 'eye' at the eastern end of the 'trunk' has an especially intriguing and somewhat eerie appearance. this may be due to a newly formed star having blown off the surrounding dust, revealing a luminous circle of reflection nebula with patches of both emission and reflection nebulae.

Processing Methods

Image acquisition and telescope control with CCDSoft V5, TheSkyX Pro and CCD AutoPilot V5.  
  Data reduction and Narrowband synthetic luminence images were created with CCDStack. LRGB colour master prepared in CCDStack. NB colour master prepared in CCDStack.  
 

Master RGB image and Master NB Image finished with Photoshop CS6. Final false colour image created and natural colour stars blended using PhotoShop CS6.
