A Field Full Of Galaxies

Hi Everyone... I hope you are having a good day..:-)

Here is an image of the Virgo Cluster in the constellation Virgo I just finished..
I shot this image at 200mm, I started counting the galaxies in this image and lost count at 50... also this is not even close to the number of galaxies that is in this region of space... I am thinking to shoot this area again at 100mm to see if I can catch even more.. :-)


The Virgo Cluster (VC) is a cluster of galaxies whose center is 53.8 ± 0.3 Mly (16.5 ± 0.1 Mpc) away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies, the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (LG) is an outlying member. However, the LG experiences the mass of the VC as the Virgocentric flow. It is estimated that the VC's mass is 1.2×1015 M? out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc.
Many of the brighter galaxies in this cluster, including the giant elliptical galaxy Messier 87, were discovered in the late 1770s and early 1780s and subsequently included in Charles Messier's catalogue of non-cometary fuzzy objects. Described by Messier as nebulae without stars, their true nature was not recognized until the 1920s.
The cluster subtends a maximum arc of approximately 8 degrees centered in the constellation Virgo. Many of the member galaxies of the cluster are visible with a small telescope. Its brightest member is the elliptical galaxy Messier 49; however its most famous member is the also elliptical galaxy Messier 87, that unlike the former is located in the center of the cluster.
