IC 1396 - Elephant's Trunk Nebula (Lucas Mourey)

IC 1396 - Elephant's Trunk Nebula

Since acquiring my monochrome camera and filters this year, I've been looking forward to the summer nebula season. Despite an almost-full moon - albeit low on the horizon - conditions were ideal at the Champ du Feu spot tonight: clear skies, a light breeze and a stable temperature throughout the night.

I decided to work on IC 1396, the elephant trunk nebula, which is particularly beautiful and photogenic.

Still getting to grips with the equipment and shooting sequences, I decided to keep things simple and shoot only Hα: this would be the first session for this object, which would require at least 3 others: [O-III], [S-II] and RGB for the stars. I'd like to do at least 10 hours in total, which will represent my longest integration time for a single image.

The processing is different from what I'm used to. There are no colors to calibrate, no real sky background. I hope I didn't overdo it.

In any case, I can't wait to continue working on this target: I hope the next few weeks will allow it!

====================================================================================

Depuis l'acquisition de ma caméra monochrome cette année, ainsi que des filtres afférents, j'avais hâte que la saison des nébuleuses d'été commence. Malgré une lune quasi pleine - mais basse sur l'horizon -, les conditions étaient propices cette nuit au spot du Champ du Feu : ciel dégagé, petite bise, température stable au cours de la nuit.

J'ai décidé de travailler sur IC 1396, la nébuleuse de la trompe d'éléphant : il faut dire qu'elle est particulièrement belle et très photogénique.

Toujours en phase de rodage du matériel et des séquences de prises de vue, je décide de faire simple et de ne faire que du Hα : ce sera la première session pour cet objet, qui en nécessitera au moins 3 autres : [O-III], [S-II] et RGB pour les étoiles. J'aimerais faire au moins 10 heures au total, ce qui représentera mon plus long temps d'intégration pour une seule image.

Le traitement est différent de ce que j'ai l'habitude de faire. Il n'y a pas de couleurs à calibrer, pas vraiment de fond de ciel. J'espère ne pas avoir trop tiré sur les curseurs.

J'ai en tout cas hâte de continuer à travailler sur cette cible : j'espère que les prochaines semaines le permettront !

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.
