Image Description and Details : PM1-333 is a small (70 arc seconds) planetary nebula in the constellation Cepheus. It was discovered by Andrea Preite-Martinez in 1988. I believe this to be the deepest, and highest resolution colour image of this target. The tiny blue progenitor star can just be made out dead centre of the image.
It lies within IC1396 where it appears as a small dot at the bottom left hand corner in J-P Metsavainio's excellent image https://1.bp.blogspot.com/-JEMi-QvpB0Q/XicHMRDQXbI/AAAAAAAARug/ECBNZGRTptwRSAOExQSKmmvCIZWz6niCACLcBGAsYHQ/s1600/IC1396Det.jpg

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.
