Two panel Cygnus Loop (SH2-103) mosaic in HOO

In this astrophotography image, I present the remarkable celestial phenomenon known as the Cygnus Loop (Sharpless 103), an extensive supernova remnant nestled within the boundaries of the Cygnus constellation. This intriguing astronomical formation reveals itself as an emission nebula, impressively spanning nearly 3 degrees across the night sky, signifying its colossal scale and celestial significance.

Drawing attention to the visual portion of the Cygnus Loop, I showcase the captivating Veil Nebula. This exquisite nebular complex comprises several distinct components. They are the Western Veil, also referred to as the Witch's Broom, the Eastern Veil and Pickering's Triangle.

This two panel HOO mosaic (my first!) allowed me to capture the intricate details and the full extent of the Cygnus Loop and its stunning Veil Nebula in a cohesive and seamless portrayal. I've also spent some time capturing RGB stars (60 second exposures) for final composition.

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.
