M8 , une nouvelle prise de 2H cette fois , jusqu'à ce qu'elle disparaisse sous l'horizon.

La température extérieure était de 21°C ( début de nuit) -> 19°C (matin) . Utilisation d'une boîte refrigeante pour APN faite maison, dernière version (x4 modules Peltier cette fois). La température du capteur a varié de 13°C pour se stabiliser à 9°C en limitant fortement le bruit thermique (post traitement grandement simplifié)

M8 once again , 2H this time . A new selfmade cooling box (x4 peltier) was used. Captor T° was stable at 9°C (T° ext : 21°C->19°C). Easier for post-processing , less "thermic" noïse

Description: Revision du Gradient / Gradient revision + colors (...)

So many differences between these releases ( same input) , I do not know what should be the best gradient option and colors on M8 An advice ? ( input=good signal/noise, not so bad)

Beaucoup de différences entre ces versions d'une même prise photo, je n'ai plus de recul , le résultat oscille pas mal . Un conseil à donner sur ce vers quoi il faut tendre ? La source est assez riche en signal et assez peu bruitée.

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.
