IC 1396 en Halpha

Bonjour

Pour changer un peu du ciel de Juillet , je vous poste ma première image faite au mois d'Aout de chez moi en région parisienne. Il s'agit de l'image en Halpha de IC1396 dans la constellation de Céphée, processée avec des images de 2017,2019 & 2020. Déjà faite l'année dernière, cette image comportait de gros defauts comme des étoiles pas rondes, trop de bruit de fond du au nombre insuffisant d'image de Luminance en Halpha et une trop grande saturation des couleurs sur la nébuleuse en HOO et SHO. Par conséquent comme pour mes dernières nébuleuses, j'ai décidé de tout reprendre à zéro en rajoutant du temps de pose en luminance ..

Comme d'habitude tous vos commentaires sont les bienvenus.

Ha : 36x600s en bin1 de 2017 + 59x600s en bin1 de 2019 + 63x600s en bin1 de 2020

Hi

To change the July sky a bit, I am posting my first image made in August from my home in the Paris region. This is the Halpha image of IC1396 in the constellation Cepheus, processed with images from 2017,2019 & 2020. Already made last year, this image had big flaws such as stars not round, too many background noise due to the insufficient number of Luminance images in Halpha and excessive color saturation on the nebula in HOO and SHO. Therefore as for my last nebulae, I decided to start all over again by adding exposure time in luminance.

As usual all your comments are welcome.

Ha: 36x600s in bin1 of 2017 + 59x600s in bin1 of 2019 + 63x600s in bin1 of 2020

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.
