Odd Galaxy NGC 3718 with Hickson 56 and NGC 3729

NGC 3718 is located in Ursa Major at a distance of 52 million light years. Originally it was thought to be a lenticular but later images revealed arms, making it a spiral. It is thought that it got its unusual shape from gravitational interaction with nearby NGC 3729, another spiral galaxy located approximately 150,000 light-years from 3718. It was discovered by William Herschel in 1789. Also in the FOV is the aforementioned NGC 3729 and the small Hickson group 56 which is made up of five galaxies.

Taken from SkiesAway Observatory over 24 nights between February 11th and March 1st, 2024 (it took a while, the winter weather was not kind)

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.
