Image Description and Details: This is the cometary globule inside IC1396, in Cepheus. It is named "the elephant trunk" due to the similarity with the trunk of this big animal. The globule contains many different protostars and it is shaped by a very energetic star in the center of the nebula complex. In this image I composed 3 different sessions: SHO and L-Extreme images taken with my C11HD from my backyard and RGB images taken with CDK500 from Skygems remote service.

The Edge of the Elephant Trunk

Taken over the course of 33 nights, this is 174 hours of exposure on an area of sky that's rarely imaged alone, but often included in wide field views of Cygnus.

This region is directly north of the Elephant Trunk Nebula, and the faint outer edge of the Elephant Trunk can be seen on the right side of this image.

This is my first image since upgrading to a mono camera, and I couldn't be happier with the switch from OSC to mono.

The object called IC 1396, also known as the Elephant Rüsselnebel, is located in the constellation Kepheus and consists of interstellar gas and dust.

The striking dark clouds of dust (globules) are areas where new stars arise. Due to high gravity, the gas is compressed further and further, so the cloud collapses. So-called protosters are emerging, which absorbs more and more gas and dust, until finally nuclear fusion begins and new stars are emerging.

The stars then make the surrounding gas shine.

A total of almost 14 hours of narrowband footage of hydrogen, sulfur and oxygen were taken and processed according to the Hubble color palette.

Hydrogen is green, oxygen is blue and sulphur is red.

This is how the different gases can be presented differently.

Image Description and Details :

The Constellation Cepheus is often in the shadow of the Hydrogen rich constellation of Cygnus but within its boundaries it really has a little bit of everything, such a varied bunch of targets. However, there is clearly a crowning jewel among the many rough diamonds. That is IC1396, the Elephant Trunk nebula. It’s a nebula that gives great color and contrast, with great areas of dust and the magnificent detail of the central trunk reaching in to the well of Oxygen that lies at its center.
