NGC 7214 in Picis Austrinus and its 'sisters' are a gravitationally bound, compact group of galaxies, designated Hickson 91 by Canadian astronomer, Paul Hickson. NGC 7214 at center, is a highly distorted SB(s)bc-type spiral galaxy, located 320,000,000 light years from us. The pronounced tidal streams (100,000 ly long!) indicate an interaction with the much smaller PGC 68155. The face-on classic spiral immediately below-left of the main pair, is PGC 68160. IC 5168 appears at
1 o'clock, with PGC 68164 below at 8 o'clock. Several other smaller members appear in this interesting FOV.
Many thanks go out to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data,
and who helped realize the core detail, which I failed to do alone.

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.
