In order to shows the most spectacular part of the Markarian's Chain, I spend a lot of time finishing my work. Markarian's Chain is a stretch of galaxies that forms part of the Virgo Cluster. Charles Messier first discovered two large but featureless elliptical galaxies, M84 and M86, in 1781.

An elliptical galaxy situated in the center of the photo is M86. The second largest elliptical galaxy in the photo which is above M86 is M84. Between M86 and M84, there is another elliptical galaxy. We call it NGC 4387. On the right of NGC 4387, there is an Active Spiral Galaxy-NGC 4388. On the right of M86 below the NGC 4388, It is NGC 4407. On the lower right of M86, It is NGC 4425, a lens-shaped galaxy. On the left of M86, It is ngc4402. Below the M86, it is The Eyes Galaxies(NGC 4435-NGC 4438). The Eyes Galaxies is a pair of galaxies. At the lower right corner, there are three galaxies. They are NGC4431, NGC4436 and NGC4440.
