Markarian's Chain & Ha Bridge

Benjamin Markarian who died on 29 September 1985 was an Armenian astrophysicist who gave his name to Markarian's Chain of galaxies in the Virgo Cluster of galaxies after he discovered that this string of galaxies moves with a common motion. The Virgo Cluster is the nearest cluster of galaxies and contains over 2000 galaxies. It has a noticeable gravitational pull on the galaxies of our own Local Group of Galaxies which surround our Milky Way Galaxy. The centre of the Virgo Cluster is located about 70 million light- years away toward the constellation of Virgo.
The Ha information is so weak that it can only be seen faintly during the processing. I compared it with the scientific research data of the 4m telescope provided by @Weitang Liang "A Spectacular H$\alpha$ Complex in Virgo: Evidence for a Collision Between M86 and NGC 4438 and Implications for Collisional ISM Heating of Ellipticals".
I performed a lot of noise reduction processing on the ha data and achieved the desired effect.and other processing, we got the image of this Ha Bridge.
Thanks to my teammates YueXiao Shen and Joe Hua.

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.
