IC1396 (CEP) The Elephant’s Trunk - A gentle giant with a memory
As the summer nights are not astronomical dark, I’m re-visiting old friends one year on, the elephant. This time with a bit more experience, fine-tuning the imaging, refining the processing, splitting the channels and processed as an HOO image, boosting the Oiii. Elephants have strong memories, as I remember the journey I’ve made since we last met.
The
Elephant's Trunk Nebula 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 piece of the
nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (
HD 206267) that is just to the east of IC 1396A
TS94, ASI2600MC

How my imaging and processing has evolved since I first captured this. Boosting the Oiii introduces a bit more graininess, but I’ve improved on the noise control, keeping the background of the image smooth, only to be put in turmoil by the fine detail that nearly 6 hours of data is giving me. Happy with the learned improvements
Clear Skies everybody! 🤩✨🔭
