Cette image est mon premier essai de réalisation d'une image HOO à partir d'une caméra couleur (ASI2400MC) et de filtres IDAS NB1 et NB3. Le Ha a été prélevé sur l'image avec le filtre NB1 (couche rouge) et le O a été prélevé sur l'image avec le filtre NB3 (couche bleue). Les 2 images ont été traitées starless avant assemblage. Les étoiles ont été prélevées sur l'image complète avec le filtre NB1. Un assemblage final associe l'image starless HOO et les étoiles du filtre NB1.

This image is my first attempt at making a HOO image using a color camera (ASI2400MC) and IDAS NB1 and NB3 filters. The Ha was taken from the image with the NB1 filter (red layer) and the O was taken from the image with the NB3 filter (blue layer). The 2 images were starless processed before assembly. The stars were taken from the complete image with the NB1 filter. A final assembly combines the starless HOO image and the stars from the NB1 filter.

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.
