Links in the chain

Part of Markarian's Chain

Well my first go at this target last year was a total disaster so this definitely better lol!

Didn't want to mess with the orientation of the camera so not the full chain

Just under two hours actually stacked

Transparency was very poor as the time drew on

Guiding wasn't brilliant , got a bit of tilt or collimation issue as have coma at the edges particularly on the right hand side

Still I enjoy looked at the details that have been captured in the various different galaxies ... not the hubble deep filed but still , a lot of galaxies !

Wiki tells us ....

Markarian's Chain is a stretch of galaxies that forms part of the Virgo Cluster. When viewed from Earth, the galaxies lie along a smoothly curved line. Charles Messier first discovered two of the galaxies, M84 and M86, in 1781. The other galaxies seen in the chain were discovered by William Herschel[1] and are now known primarily by their catalog numbers in John Louis Emil Dreyer's New General Catalogue, published in 1888.[2] It was ultimately named after the Armenian astrophysicist, Benjamin Markarian, who discovered their common motion in the early 1960s.[3] Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. It is located at RA 12h 27m and Dec +13° 10′.

The bright members of the chain are visible through small telescopes. Larger telescopes can be used to view the fainter galaxies.[2]

At least seven galaxies in the chain appear to move coherently, although others appear to be superposed by chance.[4] Six of the points on the chain can be marked by galaxies. The other two points are pairs of galaxies.[5]

Description: Started from scratch, created a synthetic flat (Having suddenly remembered how to do that!) and the result is a I think a significant improvement on the original

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.
