The Elephant's Trunk nebula (bottom middle of the image) is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars.
This is a 2x2 pane mosaic as the whole thing was too large to fit into the frame of my camera, in total there's over 60 30 minute exposures making up this image - 30.5 hours worth of images in total.
