Cepheus

Cefeo es una constelación circumpolar situada en su mayor parte en el plano galáctico, de modo que está en una región muy rica en nebulosas y cúmulos. Empecemos nuestro recorrido por la esquina inferior izquierda, desde las nubes oscuras del plano galáctico hasta el complejo nebular (y cúmulo asociado) IC 1396, que incluye la conocida nebulosa de la trompa del elefante. Incluso en una imagen de gran campo como esta se identifican perfectamente sus intrincadas nubes oscuras que se disponen de forma casi radial hacia el brillante centro del cúmulo. Justo en su límite brilla una estrella llamativa por su color muy anaranjado: Erakis, o más conocida como estrella de Garnet, una hipergigante situada a casi 6000 años luz de nosotros que hasta hace poco ostentaba el título de la estrella más grande conocida. A la derecha de estas nebulosas se encuentra la estrella principal de Cefeo, Alderamín, la más brillante de las que vemos en la imagen. A lo largo del plano galáctico se aprecian multitud de nubes oscuras y algunas nebulosas de emisión como la nebulosa del mago (NGC 7380, que también es un cúmulo abierto), la nebulosa de la caverna (Caldwell 9) y la región HII NGC 7822 (en la parte superior de la imagen). Más o menos en el centro está Arfik, la estrella Beta Cephei. Un poco por debajo de la línea que une Alderamín y Alfirk se ve perfectamente -como una estrella borrosa azulada entre nubes oscuras- la nebulosa Iris (NGC 7023). Gamma Cephei (Errai) es la estrella más brillante que se ve en la mitad derecha de la imagen. Más a la derecha, en el límite con la Osa Menor, está el cúmulo abierto NGC 188.

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.
