Galaxy cluster Abell 426 in Perseus

08/05/2019 Update. I missed an important parameter in the photometric calibration for the galaxy type, I'd keep the latest one! Main galaxies are 0 type (elliptic) and now there is the good color calibration ;-)

Abell 426, a galaxy cluster with around 190 galaxies with the biggest NGC 1275.

L'amas de Persée (Abell 426) est un amas de galaxies situé dans la constellation de Persée à environ 250 millions d'années lumière. Il fait partie du Superamas de Persée-Poissons. Il compte environ 190 galaxies sur les quelque 1 000 galaxies du Superamas de Persée-Poissons.

C'est l'amas de galaxies le plus brillant dans le domaine des rayons X1. Le rayonnement X provient de l'émission thermique du gaz (plasma) de l'amas qui se concentre au centre de l'amas. La détection de la source X Per X-1 date de 1970 et elle fut associée à l'amas de Persée grâce aux observations du satellite Uhuru dans les années suivantes.

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.
