Interacting galaxies NGC4676 "The mice" (Arp 242) in Coma

This pair of galaxies, one of the most famous of the interacting galaxies in the sky, is commonly known as "The Mice" and has also been catalogued as Arp242. It is distant of 296 mly. The North component displays a spectacular "tadpole" tail structure with a bright collimated stream of matter at least four times larger than the host galaxy. The south component shows two more diffuse strams of faint matter emerging from its core. A faint bridge connects the cores of the two galaxies and they are undoubtely physically connected. The minimum core to core distance would be 52000 ly. at the presumed distance.
This is a very small object (2.0'x0.3' and 1.7'x0.7') and I was quite happy to be able to image it with my C8 at f=2000mm and f/D=10.

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.
