The Elephant's Trunk Nebula in H-Alpha

While I was fortunate enough to collect RGB stars for my last posting of the Cave Nebula, I decided to try another target as the night appeared relatively clear. So, I slewed the C11 @ f/10 to the Elephant Trunk (IC1396A) to capture some Ha data as the seeing appeared decent. I was able to get 3 hrs worth of Ha data, good enough to get a nice close-up of this unusual area of nebulosity within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light-years from Earth. The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars. And I need to invest one day in an automated rotator as my scope is too high up in the observatory to go manually turning 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.
