IC 1396 (Elephant's Trunk Nebula) wide field

Sometimes IC 1396 is identified with the concentration of interstellar gas and dust which resembles an elephant's trunk. Correctly spoken IC 1396 is a star cluster in the middle of which is the dense globule IC 1396A which is called "Elephant's Trunk". This nebula is a site of star formation, containing several very young stars. This object is much more spectacular when imaged in Ha, hence its more occasional imaging in broadband filters. This image is a two LRGB images mosaic taken remotely from the remote controlled IRIDA Observatory and it's a part of a bigger project including the whole region.
