NGC 3718, NGC 3729, and Hickson 56: Little targets, surprising detail

Revision title: Cropped Version

This data was obtained on a whim; I was done acquiring my primary target for the night, other secondary targets were below the horizon, and I turned to the NINA Atlas to "see what was out there" searching for galaxies above 30 degrees. Randomly picked NGC 3718 and never expected to see this level of detail in a little less than 5 hours of data. Part of the Ursa Major cluster, NGC 3718 (also known as Arp 214) is a lenticular-shaped or highly disturbed spiral galaxy that is gravitationally influenced by its neighbor galaxy, NGC 3729. Bisected by a lane of dark dust, it reminded me of NGC 5128 (Centaurus A), which is a target at Dec -43 that I will likely never directly image. Immediately below NGC 3718 in this image is a cluster of 5 galaxies that comprise Hickson 56 (Arp 322). However, that group is some 400 million light years from Earth, whereas NGC 2718 and NGC 3729 are 8 times closer at approximately 52 million light years. Version 1 is the nearly full-frame view, and version 2 cropped in to show more of the detail. In the wide view far to the right, PGC35202 (UGC 6446) can be seen as a faint spiral galaxy nearly 54 million light years from Earth.

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.
