Kommentar :

Der Rosettennebel ist ein diffuser Emissionsnebel mit einem offenen Sternhaufen im Sternbild Einhorn.

Der Nebel hat eine Größe von 80.0' × 60.0' und eine scheinbare Helligkeit von +6,00 mag. Heute bezeichnen die NGC-Objekte NGC 2237, NGC 2238, NGC 2239 und NGC 2246 verschiedene Teile des Nebels. Historisch bezeichneten die vier Nummern etwas andere Sternanhäufungen und Nebel in diesem Bereich.

Im Zentrum des Nebels befindet sich der offene Sternhaufen NGC 2244, der den Nebel zum Leuchten bringt. Der Sternhaufen hat eine scheinbare Helligkeit von +4,80 mag und einen Durchmesser von 24.0'

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.
