Grus Quartet (NGC 7552, 7582, 7590 and 7599)

The Grus Quartet is a group of four large spiral galaxies that are thought to be mutually interacting. Lying at an estimated distance of 60-70 million light years, the galaxies measure 70-100,000 light years across and so are similar in size to the Milky Way. Although situated at a distance from the remainder of the group, radio wave observations show a bridge of neutral hydrogen pointing towards NGC 7552, and high starburst activity is also indicative of galaxy-galaxy interactions. Numerous distant galaxies in the PGC catalog pepper the field.

The image was collected as a two-panel mosaic over several nights in July and September. Intermittent cloud cover and some tracking issues led to a lot of discarded subs and rather variable integration times between the different mosaic panels and filters.

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.
