M42 RGB-HOO

La nébuleuse d’Orion, M42, est l’objet oculaire profond le plus spectaculaire à voir avec un télescope. En fait, la nébuleuse est si forte et brillante qu’elle peut être vue à l’œil nu. La capture de cette image en couleurs réelles ne nécessite pas de filtres à bande étroite en raison de la luminosité des couleurs de gaz. En regardant à travers l’oculaire d’un télescope, la nébuleuse semble verdâtre dans l’ensemble puisque l’œil humain est sensible à la longueur d’onde de la lumière verte, mais cette image montre que l’hydrogène gazeux rougeâtre domine la nébuleuse. Le centre de M42 est le trapèze, qui sont les quatre étoiles étroitement situées au centre de la partie blanche de l’image. La zone circulaire rougeâtre brillante entourant l’étoile brillante au sommet est connue sous le nom de M43, la nébuleuse de De Mairan.

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.
