NGC 584 Galaxy Group

This object is a rarely imaged galaxy group, led by the magnitude 10.4 bright lenticular (lens-shaped) galaxy NGC 584 located 65 million light years away in the constellation of Cetus at a declination of -7 degrees. The galaxy spans 5 arc-minutes in our apparent view, which corresponds to a diameter of 100,000 light years.

The two galaxies on either side of NGC 584 are the 13.2 magnitude galaxy NGC 586 on the right, and the 15.2 magnitude galaxy PGC 1028168 on the left. This group of galaxies is only together by our line of sight - they are not gravitationally interacting. Not much is written about these galaxies in the literature.

Although I should be PC and say that all DSO objects are my friends, the reality is that I really don't like lenticular galaxies very much. Ellipticals are not far behind. Both are tough to process, and despite my best efforts I am never happy with the result. Just not a lot of interesting structure, plus the small brightness gradient in the outer galaxy reaches makes for an unsatisfying image for me.

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.
