I have always found the Crescent Nebula a particularly intriguing and photographically fascinating subject; I took these pictures during an Astronomical Holiday in the Sirente and Velino Park, processing them with a bicolor palette HOO, which highlights the emissions of hydrogen and oxygen in the region. I also acquired a signal in SII, used for a slight boost on the G and B channels. As the main image, I use the starless version, which makes the crescent shape of the nebula more evident.For the star's version, I acquired 3 hours (one per filter) in RGB and used the three images in processing for a better and more correct color rendering of the star field.The Crescent Nebula is the remnant of a massive star that ejected its surface layer of hydrogen due to strong stellar winds. This star belongs to the class of Wolf-Rayet stars, which are progenitors of supernovae or gamma-ray bursts. The crescent shape is due to the interaction between the stellar wind of the star and the surrounding interstellar medium. The Crescent Nebula has a diameter of about 25 light-years and is located about 5000 lightyears away from us.

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.
