galaxies and an asterism

Interacting galaxies ngc 672 and ic 1727 in Triangulum. The warped shapes of these two galaxies is a telltale mark of gravitational interaction. Despite the mutual pull, there is no visible tidal tail or bridge between them. But such a bridge was shown in neutral hydrogen, by radio astronomy.
Also in this wide field (as wide as it gets with 1000 mm focal length and an ASI294 camera) is the asterism Collinder 21 (near the bottom of the image). The stars in this group are between 800 and 1550 light years distant. A bit up and to the left, next to galaxy ic 1731, is another cluster. The small red specks are the members of galaxy cluster [RRB2014] RM J015034.2+271226.1 which is at a distance of about 3 billion light years from our own Milky Way.

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.
