IC1396 / Elephant Trunk

Dark clouds of gas and dust are silhouetted against the glowing hydrogen gas of emission nebula IC1396 in the constellation Cepheus. The Elephant's Trunk Nebula is the horizontal dark region in the bottom right. Stellar winds and ultraviolet light from a hot, young star above the trunk are compressing the gas and dust and triggering new star formation in its depths. The stellar winds are eroding the less-dense gas and dust, leaving the "elephant trunk" behind it.

Description: Carefully adjusting RGB channels to get the color where I think it should be. Most of the data sits in the Red channel so manual channel manipulation took place. Used Lightness masks to boost luminance to bring out more nebulosity! We are always learning in this hobby!

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.
