Voici un objet que j'avais déjà tenté en 2013 mais avec un résultat médiocre. J'ai donc voulu le retenter pendant les vacances. Le résultat général est bien mieux. Il y a un peu de coma sur les bords de l'image (correcteur mal aligné ?) mais c'est le cadrage qui est très moyen. … je regrette aujourd'hui de ne pas avoir visé un peu plus bas… j'aurais peut-être pu avoir l'éléphant !

La nébuleuse de la Trompe d'Eléphant se situe dans la constellation de Céphée. Elle fait partie d'une plus grande nébuleuse formatrice d'étoiles, éclairée et sculptée par un amas d'étoiles nées en son sein tout récemment.

Photo prise le 20 août 2015 à Ambeyrac (12) - Canon 350D défiltré (avec correcteur de coma) au foyer d'un Newton 150/750 sur monture Orion Sirius EQ-G motorisé (sans autoguidage ni goto).

62 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.
