The Perseus Cluster of Galaxies Hi-res Annotated

This image is based on the same raw data as previous image.

I've re-processed the data to achieve a better resolution of the structures in the galaxies. The PixInsight WBPP script used the Cluster preset, which assigns higher weights to the frames with a lower FWHM. The post-processing workflow has been changed. Color calibration used the AutoColor script by Hartmut Bornemann.

Revision B has been annotated using the SIMBAD catalog. It is a bit crowded there, and still not all galaxies are listed. Please take a look at the full resolution image to see all objects.

There is a 20m quasar SDSS J032023.93+412131.5 with z=2.8 in the lower left corner.

Revision C used the HyperLEDA catalog.

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.
