The Wizard nebula is floating in its case of stars

Les dernières nuits claires m'ont permis de tester l'association de l'objectif Sigma 150-600 avec la camera ASI 2600MC. Bien que l'objectif soit d'un diamètre modeste, la qualité optique donne une image bien corrigée sur tout le champ. Les étoiles sont bien ponctuelles. L'absence de liaison électrique entre l'objectif et la caméra ne permet pas faire une mise au point sur toute la plage focale. L' ASIair donne une mesure de 440mm lorsque le point focal est obtenu. Sur la nébuleuse du Sorcier cela donne un champ large dans lequel NGC7380, même si relativement petite, ressort assez bien au sein des étoiles. C'est en réalité un amas ouvert situé à environ 8 000 années-lumière de la Terre dans la constellation de Céphée. Découvert par C. Herschel en 1787, l'amas s'étend sur environ 100 années-lumière.

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.
