Lors de mon séjour à Allons (en Lot-et-Garonne), j'avais commencé à imager le Triplet du Lion, trio de galaxies dans la constellation du même nom. Le premier essai que j'avais fait sur cet objet, en 2013, était très moyen… pas assez de poses. Malheureusement, la météo ne m'a permis de cumuler qu'une quinzaine de poses. Ne voulant pas traiter si peu de signal, j'ai patiemment attendu le 11 avril où j'ai pu prendre quelques poses supplémentaires sur notre spot habituel à Saucats. J'aurais aimé en avoir encore plus mais les brumes printanières ne le permettent pas… Ne voulant pas attendre encore une troisième soirée, j'ai décidé de traiter les 34 poses cumulés entre Allons et Saucats.

J'aurais pu obtenir mieux… mais quand je compare à l'image de 2013, je trouve celle-ci plutôt jolie !

Photos prises le 19 mars 2015 à Allons (47) et le 11 avril à Saucats (33) - 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.

34 poses de 2 mn – 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.
