Elephant's Trunk nebula reprocessed

Weather doesn't support any imaging, so I reprocessed an older image, the Elephant's Trunk nebula.

Elephant's Trunk
A detail in IC 1396 emission nebula

Image in mapped colors from the light emitted by ionized elements. 
Red=Sulfur, Green=Hydrogen and Blue=Oxygen.

The elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396.
This ionized gas region locates in the constellation Cepheus about 2400 light years away.
Formation is coursed by a stellar wind, radiation pressure, from a group of massive young stars.

Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.

At the time of imaging, the seeing was very good, HWFM ~2.5
