Elephant's Trunk - Close Up - CDK12.5

The Elephant's Trunk Nebula is interstellar gas and dust about 2,400 light years away from Earth.
The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright massive star. The entire region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars (young stars being born).

Equipment:
Taken with the CDK12.5 and the PW 0.66 reducer from our backyard over 3 nights through semi-cloudy skies.

The AP1100GTO performed admirably, tracking the target unguided through the clouds and allowing data to be captured throughout the night. The subs(exposures) blocked by clouds were then deleted.

The QHY268m with its very low Read Noise and very high quantum efficiency is a perfect candidate for the task.

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.
