La nébuleuse du croissant (ngc6888)

Premières lumières avec cette petite ASI533MC. Ça change de la CCD monochrome.
Les prises de vue ont été faites avec un gain 100, et offset 70. A voir à l'avenir pour affiner et maitriser ces réglages. Chargement d'image hyper rapide (à peine 2s) comparé à ma QSI (17s)
Pour ce 1er essai, j'ai centré ngc6888 (la nébuleuse du croissant) à 5000 AL, "visible" le long du cou du cygne. Focale 675mm avec l'extender x1,5 et filtre L-Xtreme pour la nébuleuse et clair pour les étoiles... 1h de pauses ont été mises à la poubelle, les images devenant toutes noires après calibration (notées "inf" lors du process SubFrameSelector et m'interdisant toute action). Pas compris, les brutes ayant l'air tout à fait normales. Si quelqu'un a une réponse à ce problème...
J'espère qu'elle vous plaira.

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.
