IC1318a starless (Bernard DELATTRE)

IC1318a starless

Cet objet est une nébuleuse en émission située dans la constellation du Cygne à une déclinaison de +42 degrés. Elle fait partie du grand complexe de nébuleuses Gamma Cygni (IC 1318).

IC 1318 a cinq segments désignés différents, nommés de a à e. Les parties de la nébuleuse qui sont normalement imagées comme la nébuleuse du papillon sont les parties d et e, mais ce n'est pas ce qui est montré ici.

L'objet montré ici se trouve légèrement au nord et à l'ouest de la nébuleuse du papillon. Sa désignation a été source de confusion. Vous verrez parfois cet objet référencé comme IC 1318a, mais il s'agit en fait d'IC 1318b. Il est également désigné comme LBN 251.

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.
