Sous la jupe de Cassiopée...

Le 11 septembre 2015, toujours aux RAAGSO, alors que mon 350D défiltré visitait la Californie, je mis mon appareil non défiltré au foyer de mon tube afin d'imager des objets inédits à mon bestiaire. Mon choix se porta sur trois amas situés dans la constellation de Cassiopée (sous la jupe de la reine d'Ethiopie). Le plus brillant des trois, au centre, est catalogué NGC 663. A sa droite est NGC 659 et à sa gauche NGC 654.

Ayant fait que très peu de traitement sous Toshop, je suis plutôt contente du rendu esthétique de cette photo bien qu'il existe un peu de coma sur la gauche.Mais peu importe car ce fut la dernière image que j'ai pu faire à ces RAAGSO VII et elle est plutôt réussie… vivement la prochaine édition ;)

Photo prise le 11 septembre 2015 à Ambeyrac (12) – Canon 350D non défiltré (avec correcteur de coma) au foyer d'un Newton 150/750 sur monture Orion Sirius EQ-G motorisé (sans autoguidage ni goto).

56 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.
