IC 1396 et l'étoile grenat Mu Cephei

La nébuleuse IC 1396 dans la constellation de Céphée, prise au téléobjectif Tamron à 428 mm de focale, ouvert à f/6.3, sur APN Canon 6D non défiltré à 3200 ISO.

Une 'vraie' pose d'une heure et demie, avec des expositions unitaires de 1 minute (c'est mon record actuel, je progresse dans le calage finiolé de la monture :-) !).

Et puis aussi ce soir, des 'vrais' flats, faits maison, avec l'option "écran tout blanc" d'une tablette numérique présentée à quelques cm de l'objectif (en comparant, cette méthode est carrément meilleure qu'avec ma feuille blanche et ma pauv' lampe blanche de camping... ha, ha !). Le vignettage est bien réduit avant le post-traitement.

Pas de guidage.

Empilement avec DSS et traitement avec StarTools (après un binning x2, pour limiter le bruit avec cette pose sans doute encore insuffisante). Image un tout petit peu recadrée.

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.
