The galaxy is visible with most moderate amateur telescopes at 13th magnitude. It was discovered by British astronomer William Herschel on 17 April 1784 and is a member of the Virgo Cluster.[5][3] References1. ^{{cite web|title=A dusty spiral in Virgo|url=http://www.spacetelescope.org/images/potw1440a/|website=www.spacetelescope.org|publisher=ESA/Hubble|accessdate=15 October 2014}} {{Ngc45}}{{Catalogs| IC = 3064 | NGC = 4206 | UGC = 7260 }}{{galaxy-stub}}2. ^1 2 3 4 5 6 7 {{cite simbad|title=NGC 4206|access-date=15 October 2014}} 3. ^1 {{cite book | author=R.
