Sh2-173 The Phantom of the Opera Nebula

Curiosa Nebulosa de Emisión en la constelación de Casiopea.

El sobrenombre que recibe esta nebulosa situada a 8.800 años luz de distancia es sin duda muy acertado. En esta imagen aparece mirando hacia la derecha con un gesto amenazante y la boca abierta :-)

En sus 77 años luz de tamaño se están formando nuevas estrellas, habiéndose confirmado 46 de ellas.

Durante dos días estuve tomando imágenes desde casa aprovechando que hacía buen tiempo, pero claro, con una importante Luna que hizo más difícil capturar este objeto ya de por sí bastante complicado de fotografiar. A esto añadimos algunos defectos que ha introducido el reductor de focal que estoy probando con el ED127 y alguna que otra foto con un leve error de guiado. Para presentarla en condiciones, la he reducido un 25% y así disimular los fallos.

El procesado, pues complicado también. Levantar esa nebulosa y sus alrededores es difícil con los datos que había, pero al final ha salido algo digno.

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.
