The Elephant's Dream : IC 1396 in Hubble Palette with RGB Stars

The Elephant's trunk nebula is located in Cepheus around 2,400 ly from Earth (Wikipedia). It is an emission nebula and the Elephan's trunk measures 20 light-years (APOD).

This was a lengthy project, determined by my objective of improving the SNR in the region and revealing the faint nebular structures coupled with some guiding issues. I restarted the processing a few times in order to keep the best balance between detail preservation and noise reduction (very faint details were lost even with very light NR when zooming maximally). The nebula offers a very rich palette, which gave me the impression of a psychedelic cosmic dream.

Description: This is practically a reprocess using the new Normalize Gradient Script by John Murphy, before the final integration. It brought a significant improvement in noise and gradient for the OIII and SII layer. I will start using it systematically in my workflow, it's really a game changer. The stars were also improved in the final version and I could control noise better (visible in full version, the adjusted one looks sharpened by astrobin).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
