Sadr Region without Stars (Jorge Olier)

Sadr Region without Stars

Sadr, Sadir o Sador, del árabe "pecho" es la segunda estrella más brillante de la constelación del Cisne. La constelación se localiza en pleno brazo de Orión de la Vía Láctea, una zona con extensas nubes de Hidrógeno alfa. En la imagen Sadr aparece cerca del borde izquierdo. La imagen se obtuvo en un cielo Bortle 8, con filtro L-Extreme de Optolong. Las estrellas se suprimieron con Starnet2 de Pixinsight, para poner de manifiesto las extensas nubes de hidrógeno surcadas por nubes de polvo.

Sadr, Sadir or Sador, from the Arabic "chest" is the second brightest star in the Cygnus. This constellation is located in the middle of the Orion arm of the Milky Way, an area with extensive Hydrogen alpha clouds. In the image Sadr appears near the left edge. The image was obtained in a Bortle 8 sky, with Optolong's L-Extreme filter. The stars were suppressed with Pixinsight's Starnet2, to highlight the extensive hydrogen clouds that are furrowed by dust clouds.

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.
