NGC7635 HOO V2

Salut tout le monde,Après plusieurs mois à attendre une fenêtre météo, j’en suis arrivé à un tel état de manque que j’ai recommencé le traitement d’une de mes ancienne photo.Il s’agit donc de la nébuleuse de la bulle, NGC7635.Cette photo a été acquise lors de mes premiers tests avec mon nouveau (plus si nouveau que ça maintenant) C8 edge HD. Les images sont issues d’une session en plein été donc chaude et courte. Autrement dit, on n’était pas sur des conditions optimales. Malgré tout, les brutes présentent une finesse pas si dégeu mais j’ai surtout beaucoup souffert au niveau de la correction des pixels chauds.J’ai donc retravaillé mon image en faisant une dé convolution via BXT sur les couches H et O et la souche S étant si mauvaise que j’ai décidé de faire une combinaison HOO cette fois. Je trouve que la finesse est au rendez-vous et je suis satisfait du rendu visuel de mon image. Seulement, il y a très peu de poses (2h en Ha et 1h en OIII) et je vous rappelle que je travaille à F10 puisqu’avec mon matos je n’ai pas assez de backfocus pour coller un réducteur.On sent que je pourrais tirer un peu plus sur les courbes et en extraire un peu plus mais j’aime beaucoup le rendu «doux » de l’image alors j’ai laissé comme ça.La dernière fois que j’avais publié on m’avait reproché le fait que le centre brillant de la nébuleuse possédaient un mélange de couleurs mais en comparant les photos traitées en SHO/HOO notamment de Hubble, on retrouve aussi cet agencement intriqué de couleurs. Donc comme je n’ai rien fait de bien spécial en terme d’assemblage, je vais laisser ça comme ça.

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.
