Septembre et Octobre 2023 furent 2 mois extraordinaires pour la pratique de l'astrophoto : j'ai pu ouvrir le toit de l'observatoire pas moins de 24 nuits. Un record !

J'en ai profité pour imager de nombreux projets, dont celui-ci qui reste un des plus difficiles que j'ai eu à traiter. C'est une image LRGB avec une couche Ha pour renforcer les détails et les contrastes et une couche OIII pour intégrer une version HOO de la nébuleuse planétaire.

Cette région de Céphée est magnifique car riche de très nombreux objets qui baignent dans un océan de poussières. J'espère que vous apprécierez cette image.

September and October 2023 were 2 wonderful months for my passion as an astrophotographer. I was able to open the roof 24 nights of my observatory. It's very rare for me !

Here is one of my hardest projects. A LRGB image with Ha and OIII. The Ha brings more contrast and detail and the planetary nebula is a HOO version I added later.

This region in Cepheus is very beautiful, with many objects bathed in an ocean of dust. I hope you like 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.
