Description

This area is very low in the sky for me. I took this image over several nights over a few weeks. I only get about 3 hours a night above 30 degrees. This took ages to process as was not happy with contrast and colours. Sometimes only getting a 30 mins of data a night. Found it hard mixing all the different nights different frames. Lots of gradients. It is what it is.

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
