Il s’agit d’un crop sur Messier 97 appelé la nébuleuse du hibou.

C’est l’une des quatre nébuleuses planétaires du catalogue de Messier situé dans la grande ourse. Sa distance est d’environ 45 millions d’année lumière.

Juste à ses côtés, on y trouve M108 qui est la galaxie de la planche de surf.

Sur la plan du traitement, la principale difficulté est de faire ressortir la coquille qui l’entoure. L’hyperstar m’a permis de la mettre en évidence (voir la révision 3).

Quelques passes HDR ont dû être utilisées aussi bien en linéaire qu’en non linéaire pour faire apparaître les structures au cœur de cette nébuleuse de magnitude 9.9.

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.
