Lors de la dernière soirée aux Nuits Astronomiques de Touraine 2017, le ciel était encore bon mais cela ne devait pas durer. Je lançais toutefois mes deux setups dont l’un, à la lunette, sur la constellation de Céphée. Je visais la fameuse Trompe de l’Eléphant… objet qui semble ne pas vouloir que je l’image correctement. La première et seconde tentative, j’avais mal cadrée l’appendice de l’animal et, cette fois-ci, je m’appliquais à le cadrer correctement.

La Trompe de l’Eléphant est un nuage sombre qui serpente dans une nébuleuse par émission associée à un amas d’étoiles ouvert, cataloguée IC 1396 et situé dans la constellation de Céphée (roi d’Ethiopie) à 3.000 années-lumière de la Terre. Elle a une longueur de 20 années-lumière.

Malheureusement, les conditions météo se sont dégradées assez vite et je n’ai pu sauver que 31 poses, dont certaines gardent des traces des voiles nuageux. Et c’est bien trop peu pour ce type d’objet qui en demande au moins le double. Au vu du résultat final ci-dessous, je dois me résoudre à faire une quatrième tentative… mais je l’aurais un jour… je l’aurais !!!

Photo prise le 26 mai 2017 à Tauxigny (12) – Canon 350D défiltré au foyer d’une lunette 100/900 Skywatcher sur monture Orion Sirius EQ-G (sans goto, ni autoguidage).

31 poses de 2 mn – 15 DOF – ISO 800 – IRIS et Toshop.

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.
