Sh2-173 The Phantom of the Opera

Still publishing old images taken in 2022 and hope you’re not going to be scared at this one!
That ugly face looking at us is the Phantom of the Opera Nebula (Sharpless 2-173) in constellation Cassiopeia, some 8’800 l-y away. This bright nebula by emission is faint and require long exposure to get a descent result. Here is my first try on this target during one night and I’m pretty happy the way it turned out despite the overall "pale" rendition.

This strange shape of bright and dark clouds is named after the book character of Erik from « Le Fantôme de l’Opéra » a novel by French author Gaston Leroux (1910), who is wearing a mask and « haunts » the basement of the opera house.

This area isn’t very spectacular as it has mostly dense H II regions and doesn’t show intense color variations or peculiar structures as some nebulas do around it. But it was a nice challenge at least.

Thanks for looking at my new image and clear sky everyone.

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.
