During a search to learn more about this Virgo galaxy cluster, I came across a research that highlighted the collision of the giant galaxy M86 and its neighbor NGC 4438 (http: //www.astro. yale.edu/kenney/pages/projects.html). On the majority of images taken in color by amateurs, we cannot see this interaction other than by acquiring images in the H-Alpha band. That said, the signal is so weak that even 30-minute exposures barely make a noticeable difference. But clearly, large professional telescopes are able to get this information and I challenged myself to take as many exposures as necessary to bring out the phenomenon. Here is after almost 30 hours of exposures only in H-Alpha spread over a long period given a short presence in the sky of Chile since the month of May.

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.
