HCG 68 Compact Group of Galaxies 2024

The 68th member of Paul Hickson’s catalogue of 100 compact groups unusually consists of five NGC objects, numbers 5353, 5354, 5350, 5358, 5355. NGC’s 5350, 5353, 5354 and 5355 were all discovered by William Herschel in 1788 using his 18.7” reflector whilst NGC 5358 was discovered by Stephan in 1880 using a 31" reflector. This tight group of galaxies is well placed in Canes Venatici in late Spring and has the added bonus of the bright galaxy NGC 5371 nearby. The group is located about 8 degrees south east of the Whirlpool galaxy M51. NGC 5371 is not part of the group. As one of the brighter Hickson (HCG) groups most of the galaxies should be visible in a 22cm telescope under dark skies however probably 30cm+ will be needed to see the fainter members of the group. The group appears to be at a distance of about 100 million light years. Interestingly NGC 5371 is also at the same distance and appears to be physically associated with the HCG 68 group. If so this group of galaxies may contain over 20 galaxies. The whole group appears to lie on a filament of galaxies connecting the Coma cluster (AGC 1656) to the Virgo cluster.

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.
