IC1396 - A Widefield View on Elephants Trunk

The Elephants Trunk nebula (IC 1396A) is embedded in a large ionized gas region, called IC 1396, located in the constellation Cepheus about 2,400 light years away from Earth. It dominates the image through its special shape in the upper part. The other eye-catching object is Herschel's Garnet Star on the left margin. The star also known as HD 206936 is a red supergiant and shines in a wonderful deep garnet color.

I took the image in the really hot summer 2019 in the Bavarian Forest. The early rising moon and the not yet really dark summer sky limited the shooting time to the first half of the night. Thus, I collected only 68 individual images in 3 nights. Unfortunately, I lost all my flats and dark flats due to a SSD crash in 2020, so I did the integration using only the bias frames.

Nevertheless, I hope you enjoy it.

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.
