Sh2-129, également connue sous le nom de nébuleuse de la chauve-souris en vol (Flying Bat Nebula4), est une nébuleuse en émission de type région HII située à environ 1 300 années-lumière (al) de la Terre dans la constellation de Céphée.

On peut distinguer à travers la nébuleuse une autre nébuleuse, Ou4, située à une distance d'environ 2 300 al. Elle a été découverte par l'astronome amateur français Nicolas Outters.
Ou4, également connue sous le nom de nébuleuse du Calmar géant (Giant Squid Nebula), est une nébuleuse planétaire située à environ 2 300 années-lumière (al) de la Terre dans la constellation de Céphée.

La période la plus propice à son observation dans le ciel du soir se situe entre les mois de juillet et décembre. Il est plus facile de la voir pour les observateurs situés dans les régions de l'hémisphère nord.

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.
