La nébuleuse de la tête de cheval bleue dans la constellation du Scorpion

Voici une image que je voulais réaliser depuis longtemps mais cela n'est pas facile car cette nébuleuse cumule les superlatifs :
- elle est basse sur l'horizon dans l'hémisphère nord terrestre.
- elle est située dans la constellation du Scorpion qui culmine au mois de Juin, c'est-à-dire au moment où les nuits sont les plus courtes.
- elle est faible et nécessite paradoxalement de poser assez longtemps
- elle est très étendue et nécessite un grand capteur et un instrument avec une focale réduite.
Pour toutes ces raisons, j'ai attendu six ans avant de pouvoir réaliser cette image...

Here is an image that I wanted to make for a long time but it is not easy because this nebula combines superlatives:
- it is low on the horizon in the terrestrial northern hemisphere.
- it is located in the constellation of Scorpio which culminates in June, that is to say when the nights are the shortest.
- it is weak and paradoxically needs to pose long enough
- it is very extensive and requires a large sensor and an instrument with a reduced focal length.
For all these reasons, I waited six years before being able to make this image...

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.
